agree on #1 and #3 ,  #4   . change now is now a scam and i dont heard about simple swap  .  what i like the most is binance  due to thier huge volumes  .  i rarely trade on hitbtc if ever i cant find my coins listed on binance  .  bitrex is also a popular exchange before before the dominance of binance  .

dex exchange is also on my 3rd list  , specifically etherdelta/forkdelta  because i also love to join airdrops and bounties   .  i see that ed and forkdelta were the first one's  that list my altcoins and erc20 coins
