It will stop till the set number of Bitcoins is mined. Regarding profitability, the price will keep rising and it would be profitable.
Bitcoin mining will continue even after the last bit of block reward has been distributed. That's what the transaction fees are for.
Other coins don't all use mining so why does Bitcoin anyway and if the miners make money from new coins then
how come they robbed us with transactions fees costing me $37.22 last month because something does not seem
right about this.
Because without the likes of PoW and arguably PoS you don't achieve a secure, decentralized consensus. Those alts that did away with PoW without introducing a different PoX algorithm are depending on either central verification or a set of trusted third parties, at which points you might as well use Credit Cards or Microsoft Points.
mining will never stop because that is how the design works. it can stop only if every single person the the planet stopped using bitcoin.
the "design" is that if for any reason some miners stop mining (for example like the time when they switched to mine bitcoin cash and dump it for bigger profit) the difficulty will drop and make it easier for the rest of the miners to find blocks at a normal rate (1 block every 10 min on average). and it is adjusted every 2 weeks if i understood the adjustment correctly.
Correct. Mining equilibrium will always be reached. How else would Bitcoin have been secured when it was priced at just a few cents?
Note that the difficulty adjustment period is calculated in blocks, so those 2 weeks can be shorter or longer, depending on whether the hashrate grows or declines. Same goes for the 4 year halving period.
