With bitcoin scalling problem of transactions who doesnt confirms in 3 to 4days, Verge transactions are instantly. the dream for all bitcoin lovers.
I don't have any problems moving my bitcoin around exchanges or my coinbase wallet. Maybe you need to pay transaction fees so that your transactions get mined. Thats all.. Never had a problem unless it was my fault for using too low a transaction fee.
Exchanges does pay higher than usual transactions, I think these days they are now asking for more than 50k. I don't mind setting my fee to this amount so long as its quicker but if it gets stuck still for hours, that will somehow slow down deals forcing parties to wait.
