On the moment mining can be pretty profitable business, as mining pool is rewarded for block generation, so it is reasonable to spend resources on generation of blocks. But situation will change when all bitcoins will be generated. How do you think, how it will impact bitcoins? I see here many discussions with comparison of bitcoins and banks. Is there any possibility, that block generators will turn into bank-like institutions? As bitcoin users will still need new generated blocks to make transactions, miner authority could raise greatly, as they will be able to set their terms and costs. A government institutions could also try to take block generation under control with purpose to decrease anonymity of bitcoin users, for example by prohibiting mining activities without special license. What do you think?
