By my calculations that's just a bit over 100 BTC total when adding your DGB to your BTC, or roughly $23,500.00 worth of digital currency left on a digital currency exchange. A bit risky to leave that kind of money on any of these exchanges, even if it is one of the best. They literally run on a shoe string, and even though the risk of fraud is lower in the States, the risk of bankruptcy is just as high as anywhere, and when that happens, there's no prior notice, they just close doors and then you can get in line with everybody else who had money with them. Now, I admit, everything's relative, and 23 grand to one person is another person's chump change, but regardless, the same advice holds for all: only permanently keep on an exchange what you can afford to lose. Same thing with online wallets. And be careful with security measures on your own computer. Anything online is extremely high risk. Anything on a computer without good antivirus software is high risk. Anything on a computer with good antivirus software but multiple users is still high risk. You need to really get serious to get your risk down to the level of safe deposit box safety, but you can do it. In any event, coming back to leaving money on a digital currency exchange, I'd equate it with 90% leveraged commodity trading - be prepared for it to "vaporize" at any time.
