Most tokens are like that, they really do decline their price once in the trading market. Very rare that you will find a token which is increasing in value. This is the reason why it is better to wait in exchanges rather than participate in the token or private sale. Also, is probit the only exchange for this token?
what I know is currently only listing on Probit, you can also see it on CoinMarketCap. So that you can get more information on the exchange, you should join their telegram
