The Gain/Loss metric is not good. It is based on last transaction price. I could trade a shitcoin in the Ethereum blockchain for 99999 ether -yes, almost 100000 ETH- but buying only a minimum lot, maybe 0.000002 tokens.

That's the free trick some shitcoins use to put their trash into the radar. Quite common, for example, in CREDO.

The metric is broken. Bid or Ask price should be used instead. In special as spread in cryptocurrencies are very often extremely huge.
