As compared to the Q1 of 2018, Q1 of 2019 saw a dramatic decrease in amount of investment done on ICOs. The amount collected by ICOs has been decreased by 58 times as compared to previous year.
Probably, the cause of this is because the investors have lost trust to ICOs already for being scammed and used multiple times by greedy ICOs. Well, we can't blame the for doing that so because every people learned from their mistake, and their mistake is investing in wrong ICOs.
