Who has been mining any cryptocurrency and have succeded in withdrawing his money, cause I have minied so many cryptocurrency for past years and presently now, but has not have access in withdrawal.
You should first tell what hardware have you used for mining.
Since your question is this generic, I can tell that I did withdraw when I was mining.
But I've never used cloud mining, because I understood very fast that those are scams.
And I have a feeling that you didn't mine with any hardware, instead you've gone for the nice (meaningless!) numbers the cloud mining scam websites are displaying.
