Aw it would be carnage if a forex just froze!
That's the thing though, they don't seem to realise that they are in early, so sort this nonsense out because they are earning enough money from all the trades done each day.
The Poloniex exchange has something mad like $50 million dollars in their STEEM wallet and it's not even a top 10 crypto on their exchange so it really is no excuse which doesn't give me confidence in their ability yet alone trust them with this type of money.
I understand what you are saying about Barclays and this is what we are trying to get away, the centralised banks, yes it's an exchange but it's still a bank, but I could see people flock to them pretty easily.
Just sort your shit Poloniex!!
