Yeah people need to be a bit careful with Paypal as it can be reversed and there is the chance of being ripped off.
Everybody do know about that or aware about paypals reversible transaction that's why its very risky for this kind of method on gaining profit between buy and selling bitcoin on a various price point.It may really be profitable but always mind on the risk.I would rather choose to trade with alts/bitcoin because this is much suitable for me and even earning more than 20%.
