According to ICObench (
https://icobench.com/stats), investments in ICOs were over 1.5bn in December, around 1.1bn in January and less than 200m in February (although this will no doubt increase by the time the full statistics are calculated, it seems that it will still fall considerably below the previous two months).
Average per project for previous 12 months (Amount raised/Number of ICOs)
March 2017 - 5.85m
April 2017 - 6.41m
May 2017 - 11.44m
June 2017 - 27.29m
July 2017 - 14.03m
August 2017 - 5.77m
September 2017 - 11.38m
October 2017 - 7.22m
November 2017 - 5.90m
December 2017 - 7.93m
January 2018 - 7.55m
February 2018 (ongoing) - 1.48m
In my humble opinion, this drop can be accounted for because of 3 reasons.
1. People were hoping to use profits from other investments to invest in further ICOs, then the market dropped & tied them in since.
2. Crash slowed down investment from newcomers to the market, scaring off people who were looking to make quick returns.
3. Number of quality projects on offer; there has been a huge increase overall in the number of ICOs, not all of which have the same level of ambition/innovation (to put it nicely)
I'm sure there are other mitigating factors, but I believe these three reasons definitely played a major part in the drop. Looking forward to a market recovery over next couple of months, and hopefully moving towards new all time highs by year end.
