Yeah I used to read polo's troll box when I first started trading 6 months ago, I followed a lot of the troll box complaints to reddit, over three years of complaints. Ive done a lot of reaserch regarding centralized exchanges, which made me extremely cautious about keeping coins on the exchanges wallet. Polo lost some of my sbd, it took two months get it back, they never comminicated with me when I filled a ticket, that was 3 months ago. I never traded more than 80 sbd or steem on that exchange. I like blocktrades ...it's simple lololol
