This link shows the volume of bitcoin's traded per day on most exchanges, you can see the top 3 have huge liquidity, they are also the 3 i have been using to trade most coins & have had no issues so far trading in them.. P.s. not only Bitcoin on those exchanges but just using that as an example. As always though, don't store big amounts on these exchanges & DYOR
