I quit polo some time ago. I never kept crypto on exchanges anyway, after being burnt by mt Gox. When polo started mucking around and suspending coins such as Steem, then froze my withdrawals for no good reason and took 2-3 weeks to answer support tickets I decided enough was enough.
There is something seriously wrong with this exchange. It will not survive as crypto goes mainstream. Stay away.
100% it is likely they are shouting failure to everyone, yet people still blindly use them.
