You can’t edit past cost – CoinFolio - Crypto Portfolio Review

If you remove a coin from your portfolio and then try to add it again later, the application assumes you still have your position, you can’t override this, and so if you screw up and want to edit there’s basically no way to do that, nor can you reset and start over. This app had so much potential, but it’s missing some very key functionality. Would not recommend
