This is a topic that has been discussed several times on the forum and the general outcome is that no one can predict how the scenario would pan out.
I think this is a potential problem we may see in the next few decades as the halving continues on.
Over 99% of Bitcoin have been mined already and we can already catch a glimpse of how the network would pan out over the next two halvings where about an extra 5% would be added to the total supply.
The response to this situation cannot be determined now.
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?
Miners regularly shut down their rigs or equipments due to unprofitability, although not at a scale where there's a global situation, but if the current market is any indication, there would always be miners who would replace those who left.
