The pricing data in the app (that is displayed alongside your total amount of ELONGATE tokens) come from CMC. It may not match instantly with the data on Pancakeswap, hence you can find it odd at some point that you lost some fiat value for your tokens. You can try to enter the max amount of ELONGATE that you have on Pancakeswap then match it with USDT to check how much in USD do you own now.
What’s important here is the fact that you have the tokens. You can check on Pancakeswap instead of the pricing data in the app if you want to know, in real-time, how much are your ELONGATE tokens are now worth.
