I don't know what will happen after all bitcoins are mined. but one thing is for sure bitcoin mining will never stop. because without them, the block will not be confirmed. maybe there will be very little reward that will be generated because every time the halving, bitcoin will deduct half of the reward. this will increase the difficulty.

judging from all that, one possibility is that the price of bitcoin will rise. but this is only one possibility, of the many possibilities that will occur in the future. or it could be that the bitcoin hype is fading, often increasing mining difficulty and decreasing rewards. for the problem of its influence on the global economy, perhaps seen from the level of adoption. if the adoption rate goes very fast, this will have a big impact.
