Hello. Gentlemen, I have a question. Will the mining difficulty increase after the BTC halving? Will there be no point in mining solo for small miners?
Depends entirely on price action, and there is every reason to believe the price will keep going up. As for the being no point mining solo for small miners - there's no "point" mining solo now either unless you see it as a lottery, and in that regard it will still be a lottery afterwards, just with slightly worse odds.
