I know its heresy but I'd really like to entertain a discussion on both sides regarding a concern of mine. What if transaction fees aren't enough to incentivize the miners to secure the bitcoin network? I think this is a potential problem we may see in the next few decades as the halving continues on. My hope is that we will have enough people using the bitcoin network to have a healthy fee market, but if we have weak periods like now where there are several unfilled blocks, wont miners just turn off their equipment as they are unprofitable? What options or solutions are being discussed to help mitigate this?
If the miners shut down,because the fees are unprofitable,the hashrate/mining difficulty will get adjusted,which means that mining will become easier,which means that it will become profitable again.
On the other hand,most of the miners are hoarding Bitcoins,which means that they are expecting more ATH prices in the future,which means that even if BTC mining isn't profitable all the time,a future BTC price above 100K USD might make it extremely profitable.
Even if BTC mining is unprofitable for a long period of time,many miners could switch of altcoin mining,by choosing altcoins that have profitable mining.
