I'm really done with wirex, I used to use it a year ago and I was already annoyed by all the fees they made me pay from time to time, but at least it worked. Now it's not even working, I have around $18 worth of btc in my balance, and when I try to add $10 in my virtual credit card it says "can't estimate your blockchain fee right now, try later" every fucking time, they don't even respond to my emails so I'd rather send my funds to my actual wallet and deal with the fact that I just lost time/money. Is there any other site that works the same?
