I think an underlying vulnerability in the exchange ecosystem right now is Tether, specifically its legality under banking laws in the various countries where exchanges are established and using Tether. Pegging an electronic token to the USD as a service to depositors is about as close as you can get to a bank without actually being a bank.
tether is simply irrelevant because it is not being uses as much as you think it is. the volume that it has indicates it very well.
this is a new thing that i have been seeing you and a couple of rather newly created accounts are saying! and honestly i can't see how we can even start talking about USDT while there are a lot of other things wrong with these platforms that are much bigger.
I don't know why you think that but according to
coinmarketcap it has the fourth highest trading volume, only after Bitcoin, Litecoin and Ethereum. It's responsible for about 4% of the total.
Plus it would have a much stronger effect on certain exchanges - namely Poloniex and Bittrex. This could have a chain reaction of panic on other exchanges, and combined with Bitfinex seemingly fucking everything up it could be much worse.
