I have been using this app without issues for a long time. I use it a lot to keep track of my portfolio and track what I purchased my cryptos at. It was my number one way to track my portfolio but sadly today with a swipe of a thumb I deleted a part of my portfolio. No alert, no warning just a swipe of my thumb and I deleted half my portfolio. Not once but twice. How can you make an app like this with no alert? No necessary confirmation to make sure that is what you intended? An accidental swipe on the phone deleted half my portfolio. No way to retrieve what I just deleted. At least from what I can see. Now I must take the time and investigate my point of entry all over again. If you’re a long time holder, This app will be there to make sure you throw your phone across the room when you make a bad gesture with your thumbs. Horrible horrible experience.

I absolutely love this app. It is the very best way to keep track of the alt coin markets. I would give a five star rating except for the following issue. In September 2018 I traded my iPhone 7 for the 256gb iPhone XS Max and the CoinCap app has not worked since. I reported this in a review in early October and was told they are working on a fix. So 4 and a half months later it is still not fixed. The app doesn’t open. It crashes before it get all the way open. I have the latest iOS installed and all my apps are up to date. Please please fix the app to run on this model phone. Thanks. Update March 19, 2019: After six months the programmers at CoinCap still cannot figure out how to make the app work on the iPhone XS Max. Attention programming managers and directors: You need to hire some new people that can fix this problem.

I am in complete shock. This is very unethical. CoinCap has decided to list what they feel is “correct” for market capitalization. Example: Ripples XRP shows a total market cap of 16 Billion. BTC shows 80 Billion. On Yahoo finance, they too show BTC as 80 Billion. However, XRP shows as 40 Billion market cap on Yahoo finance and everywhere else, but on CoinCap it only shows 16 Billion. Why is that. They give some lame excuse why. Real reason... market manipulation. Very convenient you can donate BTC, BTC CASH, ETH, but no XRP...? Now why wouldn’t they want any donations from the number 2 cryptocurrency in the world? I’d love to hear how they respond to this.
