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?
All the possible Bitcoins will never really be mined since the halvings just reduce the last Bitcoin down significant amounts, but it's around 2140 that the last Bitcoin is fully mined if I remember correctly. Once that happens, and realistically long before then, miners will be getting paid in transaction fees instead of typical block rewards, which will maintain the longevity of the network from that point forward. This also means that either the network will get bigger blocks or the value of single Bitcoins will shoot through the roof to facilitate transactions.
