This appears to be the coin in question: https://coinmarketcap.com/currencies/gas-town/ - up 222,513.21% in the past week! (And down 25.26% in the last 24 hours. But... suppose it goes back up again?!)

4 hours later, the 24h change is down just shy of 90%. To me this looks like a classic shitcoin pump and dump.
