The supply of bitcoin will increase but not more than the usual. New block releases into the network. Try to
Aileen, I solo mined 50BTC blocks at one point... I think I've got things figured out quite well.
Yes, its impossible to mine bitcoin more than that because the hash rate will not allow to mine any more bitcoins. Its impossible because its the total length of blockchain. So there is no solution to such an increasing price.
It's good to point out that the 21M supply limit has nothing to do with hashrate and nothing to do with blockchain length. Blockchain length increases with every block mined, it's theoretically infinite. Hashing power could also increase 100-fold over night. This would accelerate the production of blocks for a very short ammount of time, but difficulty adjustment mechanism will quickly bring the network back to equilibrium. And even if that didn't happen (which it will, it's a core component of the system), all that would happen is we'd get to 21M faster.
