Please I as answers to these questions.
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.
It is not entirely clear what you mean by the loss of access to your funds, if you mined cryptocurrency in pools and used a local wallet and did not save the private key, this is one thing. Another thing is if for payments you used the address of any exchange that ran away with your funds.

I get it cause their was one of the mining i was ask to pay certain amount before I could withdraw. But later on I find out that their was no way again to login.
And you probably have a third option is the use of cloud mining, which in fact in the vast majority of cases is just a scam, so here yes, you just lost your funds.
