Mining will continue as always, many of us won't be alive in the next 60years to this time and through all this time mining will continue as usual, the demand of Satoshis will be insane at the time. You have 0.000*** BTC and you feel it's worthless now? It won't be in the future, so relax OP and enhoy your time with Bitcoin while you still can.

I had some leftover BTC on Bitpay wallet some years ago, recently I import the seed onto a mobile wallet and I got 0.001BTC on it, free money but worth something, paid some bills with it since I have main wallet for my BTC holding, it's been there since 2017 because it was worthless.
