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 are not mining. You are wasting your time to obtain updates in the databases of a site which is useless, or you give part of your computing power to individuals who are trying to exploit it to achieve profits in return for your promise that you will get profits.
If you don't buy mining hardware, you trust meaningless promises.
