I need to buy bitcoin and fast with credit card.
Which service is the most reliable? can you guys give me some tips?
fastest should be circle if you have an international credit card, but I don't know if will be the cheapest, make sure to check all the fees and taxes you'll pay
I also like coinbase depending on level you can get some instant. And can at least buy and lock in on a price as you wait on them to get money from account if big amount of BTC. Some don't like it due to KYC rules, but it's a great way if your going to be buying/selling coins in US.
And it's insurance policy on coins in it's hands is far better then most exchanges.
