Maintaining an exact portfolio for cryptocurrency is not possible. As, almost everyone uses a cryptocurrency to buy or trade with another and fiat are generally used to buy only one or two cryptos. The prices of crypto are much volatile to keep a track of and when you are not buying it directly with fiat, you can't make a portfolio based on it.
The price may be volatile, but that's not going to stop anyone from using an online portfolio (connected up with the exchange that you buy and sell on) to be able to fetch the data from the site where you have your coins. This would, painlessly, tell you the EXACT value of your portfolio with ease.
I don't see this being such a big issue.
). I use Delta to keep a track of most of my coins and keep a spreadsheet that covers even more, but with a few airdrops here and there, and a couple of bounties starting to come through, I realised that I probably have more than I thought. Some of the coins I have received are trading already, but not on sites linked in with the app, so it makes it more difficult to keep an accurate figure on what my total is worth without individually checking each one. I guess I need to just keep a track on the main ones with the app and do the leg work on the others to find the price. There must be an easier way to do this. I have coins on a few different exchanges, plus my cold wallets, and then on a couple of web and desktop wallets. All in all, I probably have coins stored in around 12-15 different places. Anyone have a simpler way to keep a track of prices when they are not listed on main exchanges? I am reasonably well organised, but I know it could (and should) be better.
