Personally, having dodged bullets with MtGox and Bitstamp in the beginning, I learned to ID the tell tail signs of a failing or insecure exchange. I just joined Bitshares which, like steemit, is instant in transaction time. It's decentralized and pays you to hold money there, or refer people. To join under me, you could use wallet.bitshares.org/?r=htooms1 or openledger.io/?r=htooms1 to join. There are currencies , ruble, cny, eur, usd that all pay interest (5% variable) and there are coins too but not a lot of volume.
I will give up the volume and high frequency trading of Pol and Bittrex for security. I know that the governments are interested in finding out who is trading and want documentation on everyone who owns bitcoins. It is only a matter of time until the stamp out or regulate pol, bitr, bitfin, stamp and the rest out of existence.
