Would there be any disadvantage to divesting shortly before the fork and reinvesting soon afterwards? My understanding is that this site doesn't charge any divestment/investment fee. I'm confident that Ethan will come through but I'd think anybody with a large sum invested might be anxious about the possibility of missing out on the forked coins.
Well he just said that he'd credit investment balances at the time of the fork so I don't see why you'd do that. Also, there's no open/close fee on investments but if your investment is in profit since the last time commission was take on that investment, then closing it causes the last bit of commission to be taken, which would decrease your balance slightly
