I made a x5 on selfkey at the weekend and looking for other coins to invest in for medium term I think I may have found one but its not on the major exchanges so I need to create a new account with an exchange it has to be yobit or Hitbtc. Hitbtc looks like a nicer site but my main concern is scams and been able to withdraw btc if I make a profit  I have red bad things about yobit in this regard
what are peoples experience with them are they trust worthy and what are their fees like

Thanks all
