Bitcoins will fail. Part 2

My previous entry talked about what bitcoins are. I admit I am fascinated by how they work technology wise and I have been following it for years. Finance wise though, I think they fail to be a sound and secure financial instrument.

Bitcoins are safe. Everything else around it is not
Bitcoins themselves are very safe. They are encrypted and transferred between two trusted clients. However the encryption only protects access and editing of files inside the encryption, inside the bitcoin. It provides no protection of the bitcoin itself.  As long as a user has to convert their bitcoin into another currency to get its value in purchasing other things then there is a vulnerability; the exchanges.
Just last month there were three $1 million thefts from exchanges.  This is the weak link in trading and getting economic value out of bitcoins and all the thieves know it. Keep in mind how bitcoins have an ownership change. 1 wallet sends the bitcoin to another then both of them tell the entire network it has occurred. When you sell a bitcoin on an exchange there is a wallet at the exchange that you have your bitcoin in and it transfers it to another wallet on that same exchange. If the exchange is buying and selling bitcoins it has to be involved in the process. The only way this can occur that I am aware of is if the wallets are controlled by the exchange and you are given access to the wallet.

There is no rule however that says you have to be the one initiating the bitcoin transference. In the linked article above, one exchange just shutdown and kept the bitcoins. They can then transfer from the wallet they control to their own. Both wallets update the network and everyone is in agreement on who the owner is. Some users are openly admitting they stole the coins because why not, there is nothing that can be done to stop them.
In reality you never own a bitcoin. The wallet owns the bitcoin. A person doesn't even own a wallet its a matter of who is controlling the wallet at any given point in time.

Exchanges aren't the only access point that is vulnerable. There is the connection between you and your wallet that can be denied on your own computer through malware. If encryption protects the editing or manipulating of the bitcoin from being copied and created then a second layer of encryption can protect the first encryption. So one day you go to access your wallet and an encryption key is requested to access your wallet. Oh and a helpful popup appears saying if you want to know what the key is you had better get to a second wallet and transfer a bitcoin to the listed wallet address. If not then the wallet is deleted. Remember that nobody can just create bitcoins but nobody said that a software file cannot be deleted. Or lost on a hard drive computer crash for that matter.

Anonymity is a double edged sword.
One of the big selling points of bitcoins is that its anonymous and its nobody's business but yours and the person you are sending the bitcoin to. This also means that if a bitcoin is stolen there is no way to prove it. You cannot go to the police and tell them that John Smith stole your money and you want it back. The entire bitcoin world is in agreement that its no longer your bitcoin.

Remember the whole part about the government cannot track or regulate bitcoins? That also goes for them sticking up for your rights. When cash is in a bank and its robbed or the bank goes bankrupt the FDIC (Federal Deposit Insurance Corporation) steps in and replaces your cash because its just cash and not unique.The value is just replaced. For protection of stock brokers closing shop we have a similar protection with the SIPC (Securities Investors Protection Corporation). These entities insure that there can be no fraud that will hurt the individual. There are undo buttons to reverse transactions. This is what also allows credit cards to work. Yes you can have your identity stolen and someone run up credit card bills but in the end, the system is intended to get everything reversed eventually and for you to not be left with having a financial loss.

Bitcoins are software so theoretically it can be changed and edited to allow a black list of bad bitcoins that are not accepted. Now you have a problem of a central authority making decisions of what bitcoins are good and what are not which goes against the idea of what bitcoins are.

Bitcoins are still software
A bitcoin's history is public record from the moment its created to the current date. Each time it changes wallets its recorded across the whole network so that everything is legit. Bitcoins also go out to 8 decimal points. Wallets can be created at any time and people can have multiple ones.
Do you see the problem with this as far as the network becoming bloated and bogged down?
Wallet #255,327 sends bitcoin #3,425,854.04938593 to Wallet #3,994,329. Now given enough time this Satoshi (part of a bitcoin) will get passed around that it's trail gets larger and larger for everyone to verify that its latest transaction was legit. The more popular bitcoins get the more bloated the system and slower it will become.

Currencies have to have faith
It is faith in reversing wrongs and being protected that is one of the reasons fiat currencies work. A person can have the sense of freedom that when they use their credit card or spend their dollar it will be accepted by the merchant. They can also feel secure that if their identity or credit card is stolen and used that they are not left responsible for the damage. The damage can be undone. It may take time and isn't full proof but that is the intent of the electronic dollar system.

Currencies have to have stability
This is perhaps bitcoins greatest weakness imo as to why it will never be a successful currency. A currency needs stability and faith on its expected purchase power. That's why the Federal Reserve is careful not to have deflation at all and only a little inflation. This way day in day out people have a general idea of what a dollar can be used for and thus make plans, investments, and informed decisions about their spending habits.

Bitcoins on the other hand changes 30% or more of its value... in one day. It would be like walking into the grocery store to buy that steak for $10 being told sorry it costs $16 today. But come back at the end of the week and it will cost $7. Compound that out several digits and now the bitcoin system has some major problems.

The upward shift in purchase power causes hording. That is speculation on my part but let me ask you this. I remember bitcoins going down to $0.01. A year ago bitcoins were going for about $20-$30 or so. A month ago they sell for $600. Today they are over $1,000. Are you going to trade your bitcoin for a good or service like you would a currency or are you going to hold it to sell later when it appreciates. Talk to Laszlo Hanyecz who did the first online bitcoin transaction back in May 2010. 10,000 bitcoins sent to another person and the other guy paid for a delivered pizza to his house spending $25. That is ten million dollars in today's value. In 3 years time.

This is an asset not a currency. Bitcoins might have value as an asset to convert into dollar profit. That is of course if you can maintain control of your bitcoins vs the dangers I listed above.
I freely admit I am no expert on bitcoins. I have never controlled one and probably never will. To me, there is too much risk and not enough reward via guarantee. However we have historic precedence of what happens without regulation of a currency and regulation of markets or even asset class mania.

Bitcoins will fail. Part 1: Whats a bitcoin.

It seems like the world is going crazy over bitcoins as an investment and currency to replace the dollar. I wanted to give my view on it.
Bitcoins suck and you cannot take them seriously.
Alright so I've probably offended some so let me explain. Bitcoins sound great on paper but when you start thinking beyond what they are and instead focus on how they work the whole bitcoin story falls apart.

What are Bitcoins
Bitcoins are encrypted software files that are generated by a software client solving mathematical equations. Anyone may download and install the client and have their computer start solving these equations. All the clients communicate and update each other. When one of them solves one of the equations it notifies all the other clients that it was the first. Everyone else gets locked out of that equation and they all move on to some other equation.

The client that is credited with solving the equation creates 1 bitcoin. It is encrypted and tied to that client. It can be given to any other client and then both clients will update everyone announcing that ownership of this file has changed clients. If anyone tried to copy it to create an extra bitcoin the entire network would deny it because it doesn't follow the publicly known trail of ownership.

While bitcoins and their trails are public knowledge, who is using the client is not known. In this they are anonymous. Its not John Smith using his debit card to transfer dollars from his account to a store's bank account. Its Client #2,845 sending bitcoin #5,943 to Client #19,404. The reason why it was transferred is not recorded or known. Only the act of transferring ownership is transmitted. Bitcoins are stored in "wallets" and transferred to other user's wallets.

Why are Bitcoins valuable
The fact that they cannot be created easily gives them rarity. A person cannot Ctrl+C and Ctrl+P and create bitcoins so there is a limit. There is also a maximum amount of coins that can ever be created. The more mathematical equations that are solved the longer it takes to make the next one. Plus there is a limit as to how many equations were setup for the network to work off of. Now while the maximum number of bitcoins is in the millions and they can be broken up into 8 decimal points of bits of bitcoins, there is still a limit.

What was the intent of Bitcoins
Bitcoins were created as a way of having decentralized currency out of the hands of governments and the financial establishment. Fears that governments can turn on a printing press to create fiat dollars are avoided because nobody can just create bitcoins just as nobody can create gold. Without knowing who is behind the clients then users can avoid taxes and be out of the reach of national governments. The U.S. can pass a law about bitcoins but they have no way of knowing which country a user is in. This allows a person to do what they want with their wealth.

How are Bitcoins used as a currency
You cannot use bitcoins to purchase things directly. You have to convert it back and forth into dollars (or another national currency). Yes I know some websites will allow you to transfer bitcoins from your wallet to theirs and they will give you a service or good but they then have to convert it to dollars to pay their distributor that sold them the cellphone they sold you. Until a company harvesting natural resources used in the manufacture of a product takes bitcoins then it is still tied to a currency.
However there are exchanges that people have setup so that bitcoins can be turned into dollars and vice versa to get around this problem. You create an account with this exchange and connect your wallet to it. Just like any forex account, you can buy and sell one currency for another.
So really how the whole buying things for bitcoins online works is that you converted your dollars into a bitcoin, you send your bitcoin to someone who has agreed to ship you a good or service, they convert their bitcoin to a dollar because they need to pay rent on their office and pay their utilities and taxes.

But aren't bitcoins created by a computer program? If you bought a bitcoin from someone yes you converted your dollar into a bitcoin but what about when it was first created by the client. There are no manufacturing costs there? Actually there is. Electricity. It takes a large amount of processing power, time, and thusly electricity for a computer to create a bitcoin, commonly referred to as "mining" a bitcoin. For awhile it cost more money in electricity for your utilities then what a bitcoin was worth. Let alone the mining computers that they have. If the first computer to solve the equation gets the bitcoin then the biggest and fastest computer has an advantage. They do. Graphic cards had the best processors for solving these and people were buying 4 or more at a time to put into one computer. There were lots of Youtube videos showing elaborate setups with multiple computers working side by side. Bitcoins are past the time that an average person is going to be able to realistically user the home PC to mine some bitcoins. The early adopters could and did but that time has past.

Up to this point it sounds great and I admit that I am fascinated by the technology behind bitcoins. I do think its an interesting idea. However when we start seeing bitcoins in practice it losses its appeal. I'll get into that in my next entry...
