While I understand, that mining is only beta, and thus it is difficult to answer without delay such an easy question, if our mined coins will be safe, now I see another glitch: for several hours, pool blocks are adding up, my hashes are adding up, but my "total due" stays the same. This is probably the reason of total network hashrate drop, isn't it?
I am burning my electricity and capacity to this and I am not sure, if I should continue mining now.
