I guess you're not just finding out that Bitcoin has a fixed supply of 21 million coins. Yes you read right.
This is not the first time we have been seeing or hearing this. You were a good ready in the forum, you must have seen it in the forum either in the beginners & help section or the bitcoin discussion board.
My point is, do you think other crypto currencies will adopt such policies to keep up, or rival Bitcoin?
I think every cryptocurrency which I have encountered had a limit on the supply. Ethereum has a limited supply and others so it is not some new to any active forum user.
