Have you ever wondered how the future of crypto land will be once all Bitcoin are mined by 2140? By that time, Bitcoin miners will be living off fees. It's expected that Bitcoin's price would be high enough to help sustain miner's operations. Bitcoin could be well worth over $1m by 2140, if all goes well. There will be a lot of demand for altcoins as digital cash, while Bitcoin will be the world's store-of-value asset. Scalability and privacy may no longer be an issue within the Bitcoin blockchain, as developers would've found a way to make the pioneer cryptocurrency useful for the world.
While we still have a very long way to go for this to happen, it's great to imagine how the future of Bitcoin and crypto will be after a century since their inception. I'm curious to know what do you think Bitcoin's future will be after 2140? Your input will be greatly appreciated.
Bitcoin mining will become unprofitable probably a 100 years before that, so what you say will probably be experienced in our lifetime. This does not mean higher demand in altcoins, Bitcoins are scarce and thus more valuable. Just because you don't make money mining bitcoin does not mean it loses value, most of bitcoin's value is unrelated to mining (contrary to some beliefs). See after each halving bitcoin mining profit gets cut, as it was designed to, and the same happens to miners, because it is a transition to the stage where most bitcoins that there ever will be already exist and no more are coming (or take so long to come that its pointless to wait for them).
As i keep telling people, bitcoin price isn't rising to compensate miners. It does go up, but at a lesser rate than mining. Mining was, since the beginning, a temporary thing. Those that made models thinking mining will remain forever, where wrong since the beginning. You can't possibly expect endless mining with a coin with finite supply, this is how flawed that thinking is. But unlike an abrupt ending, the halvings make for a a smoother transition. Miners have the chance to plan their exit, as many have done.
Sooner than later, the only mining will come from hobbyists and those with "free" energy. By then the hashrate and difficulty would have gone down, but since its unprofitable anyway most won't bother. Bitcoin will go on just fine, of course.
My view about altcoins are contrary to yours. There are simply too many, most are destined to die. And people are not going to bother carrying 100 different types of coins. The only thing that matters in the end is: Can it be exchanged for bitcoin? And that is that. If a second or third altcoin manages to survive and get used, it would be a miracle.
I have warned miners before that the time to diversify or even venture into other business with the money they got from mining is now, and every day that passes, if they don't shrink and switch they will end in the red and lose all.
