No problem. We might just watch what happens at polo, if there is a more serious problem. I keep thinking about the things they have done lately doesn't make sense. First they kick out two dozens small-caps, then they disable the troll box. It doesn't add up to good business sense. Kicking out revenue? Disabling their users favorite toy?
I have on the other hand successfully deposited btc and withdrawn the resulting nem without any trouble.
Yes, I was worried too and withdrawn my BTCs without any problem recently.
About the trollbox, it was quite useless, admins were constantly banning people when they announced some crypto dump / pump, the rest were just support requests.
