Storm is really very good project, but i don't know why price are decreasing day by day

I totally agree with you, storm is a project, I guess the price decrease is due to btc going down day after day as majorly all coins and tokens are paired to it, so whenever it goes down in price, it affects the entire crypto market just as it does when it rises
I think so too. It is likely that in a positive market, the storm will be irresistible. I hope to see this this autumn.
