Agree, we cant use exchanges as coin safe deposit.. Still wee need them to do trades, will be use an exchange that continously give people trouble?...
We all pray for a decentralized exchange, that would solve so many problems and will give us a big relief...
I prefer to keep them in my own wallets and trade them in THIRDS via BLOCKTRADES.US & SHAPESHIFT.IO when I see a WINDOW of PROFIT OPPORTUNITY!
Blocktrades is good!... Altought most of the time trade rate are bad, exchanges will give you higher profit... Havent tested SHapeshift.io yet...
But never use poloniex...
