Hi.
I'm thinking of start selling bitcoins on localbitcoins for paypal and stuff, but I need to know which best way to double bitcoins is it cloud mining? investing or trading?
comment below, and no spam and this will be self moderated to avoid spams from ads posters.
thanks

Most of cloud mining sites have turned out to be spam nowadays except some sites like genesis.
I have no clear idea about investing.
Trading is the best option for earning bitcoins.Trading could be started even by investing a very small amount.But experience is needed to minimize the risks and losses.
