Hello. I am from Eastern Europe. I have been on solo.skpool for over two years. If I switch to eusolo.ckpool, will all my shares be lost? Two years of mining for nothing?
In any case, any share that is lower than the current BTC difficulty is always ‘for nothing’. Anything that is not a block is ‘for nothing’ with solo mining. The work previously done is of no importance, only shares equal to or greater than the current
BTC diff count.
You can switch to the EU pool with no hesitation, it doesn't really change anything (except that you'll work with a better latency).
