A question to the older members here would be to ask if there was this much worry and fud in the last halving? Surely back then miners where in the same situation that if we never got a price rise then it would become unprofitable to continue to mine and miners would drop out left right and centre. yet we are at another block halving and miners are still doing their thing.
Back then, we still had shitloads of hobby miners with GPUs. Hobby as in "I do this because I think it's fun."
Right around halving time the first ASICs came out. A quantum leap in hashrate, obsoleting all the FPGAs/GPUs.
