Circle is behind USDC stable coin and intentionally designed it with a backdoor to be able to totally control it. In other words, they can freeze user funds whenever they want it. Is it safe to invest in a "stable" coin with a feature like that? I don`t think so.

Cant withdraw my money from poloniex, support ignoring me, I dont know what to do, People pls use another platform to trade, Dont repeat my mistakes

Use a different exchange. This exchange is owned by Goldman Sachs. He manipulates cryptocurrency so he can make money from those who freak out when they wake up and hear his remarks posted in the middle of the night I switched to Robinhood. It was a little harder to use at first but I got the hang of it.

Closed my account once I submitted my documents for verification, reason being "to protect our customers." Right.... Sure, go ahead, use them, if you like being treated like a criminal. My best advice would be to use another exchange. Be sure to use exchanges with only stellar reviews because this is YOUR MONEY you are trusting them with.

support not good

Well they no longer facilitate Bitcoin transactions. According to a blog post in December, Circle no longer permits "the ability for customers to buy and sell bitcoin directly on Circle." Instead, they are "introducing a new preferred bitcoin exchange partnership with Coinbase." As for a digital wallet–Circle offers a quality product. It's easy to set up and their security protocol is good. They should continue to publish blog posts and explain their decision to end btc exchanges.

Ease of use and access is marvelous, transactions are free (aside from CCs), and I can message my fiat friends on the app while not blasting my information for the world to see (cough cough Venmo)!

would give 6 stars if possible. was almost scammed by CEX.IO, and would have been if my bank didnt notice before they drained my account. have almost hit my weekly BTC amount on Circle with probably 10 BTC buys from them, and not one of them have taken longer than 10 minutes to receive, some were instant, and havent had one single problem with not receiving the BTC. constantly updates BTC value. have no bad experience to list. love Circle, and they now have a loyal customer for good.

Very nice legitimate service. Haven't had any issues besides instant transfer caps, which isn't much of a complaint because this is the only place I can get instant bank transfer credit. While not a full fledged exchange by any means, terrific for the everyday person who wants to purchase something in BTC simply, easily, and cheaply. 1 star off since I would love more of a trader-friendly system, but I see that it isn't set up for it. Either way, already recommended Circle to my other friends who need BTC.
