I can tell you why.
First remind cryptocurrency market is increasing and is still doing so.
Everyday new investors are coming everyday.
This exchange coin is a sleeping giant.
Please have look at at BNB from Binance and KCS from Kucoin.
They started similiar with small prices and are now both in the top 100
with around 20$ per coin.
COSS is around 2$ now like you say, made a rapid jump already and this is not over yet.
This will go the same way at least 10x or more I predict for this year.
So jump on the train you r still right in time to make really soild and safe GAINS !
