ICO Token has some value on the market but not in the wallet

Hello everybody, I used to be making an attempt to study extra about initial cryptocurrency choices and transactions. So I just invested 100 bucks to a newly created token. So I purchased the token at a very low cost worth and its value elevated too much in only a day. However when I attempt to swap it, I had some type of an error. The day after its value was zero in my wallet, however it even increased in the graph. I've no clue. Thanks
