What is the safest way to earn regularly and securely from cryptocurrency?
I don't really understand what you mean.
I think in this discussion you have to be clearer to ask questions or opinions.
but ok
in Crypto currency, none of which are completely safe are all potentially and risky. what else about the amount of altcoin that has spread. So, essentially you have to have knowledge and always involve experience to research first before you decide to speculate.
