My own guess is that it's some air being let out of the bubble. Cryptos have been on a tear and this is healthy imo.
A lot of ICOs lately and just as with the dot com bubble, some are really great companies while others shouldn't see the light of day. Who knows when the major shakeout will occur.
Thanks... I think it's healthy as well, seems like it was creating it's own bubble. Glad you said something about the dot com bubble, I've sure been feeling that it really seems like we've been here before, probably have... only worse this time around...
