I think bitcoin makes on sense at all.
A decentralized money means every client holds a central bank -- it's feasible only for a very small scale. The block chain is 10G today. It can grow up to 100...0GB if it wants to get the same position as usd or euro or cny -- obviously it's impossible.
It's no better than an idiot comapring to current finacial system. It does not support transaction, rollback, tracing, etc.
When more people get involved, it will be a nightmare.
When SHA is hacked, everything is gone.
The rule for wealth is so ridiculous -- btc mining likes lottery. Is this better than rules in today's real world? No, it's just ridiculous.
It's just a new kind of Ponzi scheme. Everyone hope his btc will become more and more expensive so he can get rich without doing anything. I do not think they will succeed.
Am I wrong?
blockchain can be shortened through various methods, although i do admit it is a big weakness because of its size
