Does this mean that all the work I've had is in vain?
and that all mined coins will be lost?
No it does not. We are still in the correct chain, so your coins are safe. It is just causing trouble with mining enough for the demand. A bunch was mined yesterday and payments were pushed. You should see them in your wallet.
Thanks.
hello friend, thanks for replying, I already received a payment, half already in my wallet, good work.
