Coinbase

Coinbase is an OG of the crypto space and personally I have never had a problem with security so I can't rate them below 3 or 4 stars. However their customer support is lousy, they charge pretty high fees, and lastly don't offer a wide variety of products. Thankfully, they have been developing their coinbase wallet as well as other tools that will keep them competitive.

Massive scam. They will steal your money. The Fees are ridiculous and they just don't pay out the rewards advertised. They advertise that some crypto you can get over 5% a year in rewards but they just flat out don't pay. customer service is basically non existent. It took customer service two hours to tell me they couldn't help with the problem. Most of the time was spent "checking the issue". After leaving this message they suggest trying to contact customer service. Please save your time and money by choosing another service.

I used this crypto exchange at the beginning of my personal crypto journey. However, my account was suddenly blocked without any clear reason (at least in my opinion). I didn’t lose a lot of money, but it was still an unpleasant experience.

I had a bad experience with this app. Network issues are the most annoying things to happen. I had to restart the app dozens of times before it worked fine. I've already lost an hour.

Best crypto app. The interface is great and it is super easy to buy/sell. I am also using their API for python.

It is one of the best in the market for bringing newer people in the space, but does have high fees and limited access to lots of the crypto ecosystem.

Still exploring the wallet, its very user friendly, has a friendly user interface,

its great. Real time market values.Easy to make trades. Great learning program.
