Bitcoin affectionados beware, if you are looking at IQ Option as a quick way to upload cash from a credit card, exchange for Bitcoin, and then transfer off, don't!
I uploaded cash from a credit card, exchanged for BTC, and sent an immediate withdraw request on January 3rd. I only YESTERDAY, the 17th, received the Bitcoin after many long, agonizing phone calls and live chats with (albeit responsive) various customer service reps, which means it took them 14 days for withdrawal. So...
do NOT use IQ Option! It's worse than pulling teeth!
My only positive feedback is that I could always reach them. Their laborious and slow withdrawal process, however, negates any positive feelings towards them for that.
