There are only 21 million total bitcoins that can be mined, what will happen if all bitcoin is already mined?
According to research if bitcoin reach its limit, it will be disappear but it doesn't happen already so don't worry. I think devs will solve the problem to extend.
This is a BS, How come that bitcoin will disappear it was mined. Where do you find that information? After all BTC mined, All the miners will still have profit from processing transaction. Imagine if all bitcoin was mined, The volume of transaction per day will inflate and that means a lot of job and income opportunity for investors that time. But bitcoin scaling might resolve first before thinking this matter.
