| Doesn't make them wrong. I find the idea of crypto currency, especially bitcoin, very interesting. I just have a very hard time seeing how it's actually useful. It can't handle very many transactions per minute. And the thing that supposed to make it so great is that no one controls it. But if bitcoin becomes really important then people will want to control a lot of the mining power. Pretty soon you end up with a group of miners (or even a single miner) having enough power to influence things leaving you pretty close to someone being in charge of the thing. It's such a fascinating idea. But in less there was someway to limit mining so people couldn't throw additional power at it I'm not sure it's useful. As an example, you could use a block chain to enforce a ledger between a couple of different companies but you'd have to have some sort of contract it said everyone was only allowed to use one of device X for mining. That way everyone would be equal and you could easily check it because the blocks should be minded roughly evenly. But when miners can buy additional mining capacity, and they get rewarded for doing that with more money, how does this not end up with a winner takes all situation? |
