It's not just Mercury. ICOs raised 800M in Sept, a record. Oct. projections are closer to $200M, a severe correction. This owes perhaps to lower performance from ICOs; if true, October's returns will be even lower (judging by TokenData) and I don't expect us to rebound to late-summer, early fall 2017 #'s anytime soon. Many of those throwing ICOs in Oct. have been surprised by lack of interest. The BTC fork is not helping with many investors staying locked in Bitcoin until Nov 16 (B2X). Yes the crypto-investor community is not the most rational and makes most decisions based on social proof. ICO's be warned: the old, build it (the ICO), and they will come is over. Crypto co's cannot take it for granted; like it or not, co's have to revisit their assumptions and redouble their marketing efforts.
