Why does my token have no value?
Starting March 2020, the app will only show the price of tokens with a minimum trading volume of at least $10,000 USD and a Market Cap of $10,000 USD or higher.
This is applicable only for tokens that is showing on Coingecko.
This is still subject to change if deemed necessary.
