After the last bitcoin is extracted, will it become a mass payment unit in the world? Its price on crypto-exchanges will be stable? Share your thoughts, I'm very interested.
The thing that scares me most about the mining to end is the prices. I mean there is two options, after bitcoins are done mining (well it won't end for a long time but it will be really low amounts over time) the fee will be the only thing miners will be making money. So, the two options are, either miners will keep the fee high or keep the bitcoin prices high so it would worth their time to keep mining bitcoin or they will leave the business which would mean bad things for bitcoin. I do not know which one will happen but if the second option happens than we are not looking at a great future for us so we should find a solution to that.
In some assumptions, after ~100 years (or before the last bitcoin will be mined out), the total TX fees will be included into one block may sum-up into more than 50 BTC also (which is the original block reward). Then, why miners will go away and how bitcoin network will be unsecured ?
You are mentioning about the third possibilities. Yes, I must agree that when the last bitcoin will be mined out, the number of transaction will be occurring on every 10 minutes will be something unimaginable hence the sum of transactions fees alone will be enough for miners.
