This is my biggest issue. I'm not able to take advantage. For example: I got a great deal on some ETH on an exchange, and saw it trading 12% higher on Bittrex. So I initiated a transfer to swing it over to even look for a 8-10% gain—not being greedy. The ETH took an hour, and by the time it was available, all those gains had evaporated.
I can't afford that.
