What's the best app for buying/selling bitcoin & ethereum?

I don't use Coinbase personally, but I hear a lot of good things from people who use it. EDIT: I now use Coinbase and love it. :)

That's what I've been using because it's simple, mostly safe (I wouldn't keep my 💰 there, but I know they have a "vault") and UX is not bad. I tested other services that were trying a bit too hard to present buying crypto as if it was an obscure activity (or maybe they just didn't care about good design) made only for guys living in their mom's basement; wasn't for me.

I'ld rather use a non-mobile Website which I now is super secure, instead of an app like Coinbase where practically everyone can join.

This allows you to buy Bit and Eth, also works worldwide not just in the United States.

I also use this, primarily because its one of the few that supports worldwide payments. The user interface is also nice and well thought out. The fees are bit on the high side for my liking.

For the more paranoid, LibertyX is a great alternative to Coinbase or other online exchanges. Purchase a QPay pin from one of thousands of their partner stores (usually cell-phone shops that sell prepaid SIM cards) with cash, put the pin into their app, and enter the address you'd like the bitcoin sent to. It's instant as well - Coinbase can take up to a week if you pay using a connected bank account - which can protect you from bitcoin price volatility. Trading that into Ethereum is relatively simple - use kraken or any other bitcoin exchange.

Great option if you don't have access to traditional banking methods or can't wait the few days Coinbase takes to process. Pay with cash, credit card, direct deposit, all in a p2p marketplace

I sold my bitcoins due to the downturn of its price easily at cryptoexmart and my cash was transferred to my bank account immediately. These guys are fast and they charged me about 0.01% for selling $85,000

they always deliver timely

Great mobile app to compare bitcoin price in website which selling.
