There is high possibility of it happening. Mining is a costly business to start and it also needs a good amount of recurring cost to maintain. So if bitcoin price isn't increasing now, a lot of small miners will be forced to leave mining because it will be cheaper for them to buy bitcoins from the market instead of mining it.
However, we haven't seen any signs of it. Let's keep a close watch on the situation. It seems bitcoin won't disappoint the miners.
Probably it is possible because we all know that mining is much more expensive compared to the bitcoin's price that can be cheaper due to the halving effect. Many miners will surely invest in using crypto instead of mining because the incentives are also important. It will not be profitable for them as they see that costs in mining will become more higher compared to the mining costs before halving. It will surely give you lesser amount of profit and that will make you lose the advantages of mining. I know that many former miners will invest in bitcoins because they will see that it is much more profitable than mining. That's a good option and choice to do, investing in cryptocurrency will really make you more comfortable with your business and work.
