Interesting. It over than 15 mln of bitcoin have mined already and as we all know the limit point is going to be 21 mln. So I'm asking do they going to concentrate only on bitcoin mining which is going to be over in few years or some other crypto as well? But the idea is great.
I don't think you fully understand all the facets of Bitcoin and mining. (Not that I understand it all either...)
Anyway, Bitcoin mining will NOT be over after all the coins are mined. The Bitcoin network will still need miners to confirm and process transactions. The miner's payout then will consist of transaction fees. Without the miners, Bitcoin could not function as a payment form since there would be no way to process transactions.
That is my understanding anyway. If I'm wrong I'm sure someone will correct me.
