I don't either. Holding a 30% dip leaves a lot of BTC that could be had, on the table.
That is why so many traders are using USDT, so that means it is huge centralized vulnerability in the Bitcoin ecosystem! Even more huge than Bitfinex. On par with Mt. Gox.
USDT is used on Poloniex also! The Bitfinex hack caused a -33% crash. Mt. Gox caused a -90% crash.
I would guess maybe a USDT failure will come later when BTC is at nosebleed prices again. Perhaps not enough Bitcoiners use USDT yet, so give it more time to become more widely used.
