There's always going to be a group of miners that will remain profitable- that's just how mining works, and difficulty adjustments will make things more profitable eventually. Mining will always continue on major cryptocurrencies, as even if people stop mining, difficulty will eventually correct itself to make mining profitable again, and blocks will continue to be mined.

I've personally chosen to turn off essentially all my mining rigs and I am currently just purchasing and holding cryptocurrencies. Many others on this subforum have chosen to do the same. Just keep in mind that if you're mining at a loss, you're essentially buying coins at market price plus electrical and maintenance fees- not an ideal situation.
