Hello, when do you guys think all the bitcoins will be mined?
I think bitcoin will not all be mined, it is impossible. Because bitcoin is like money, and money just circulates around, and I think the same principle applies in bitcoin. So, we don't have to worry because it will not be drained at all.
BTC will eventually all be mined. The mining rewards halve at a pre-determined rate. Once all the coins have eventually been mined, the miners will then be mining solely on transaction fees, which as long as the coin is being used on a regular basis will be enough to keep it alive.
