Hi Today I opened the app and it says my crypto is down 70%, saying next is worth 0.29 USD? This is weird as my portfolio app and CoinMarketCap cap say its double that. Am I missing something My Nash stake is over after 2 years, I made 11 USD in dividends, woop! :) Can I do anything with these tiny amounts of BTC and USDC etc, about 6 USD of each?
