I'm gearing up to start investing in BTC and possibly ETH. I see there are P2P sites such as Bitbargain for BTC and exchange sites such as Coinfloor. When it comes to cryptocurrency, is one route better than the other (e.g. additional layers of security) or, as long as you choose a reputable site, is it basically six of one and half a dozen of the other?
Never ever heard of those sites. The only big major one I know starting with Local******* I wouldn't recommend as they are a ripoff when you withdraw.
