Ari Paul, CIO of cryptocurrency hedge fund BlockTower Capital, talks with Business Insider executive editor Sara Silverstein about why he thinks investors should be cautious when investing in ICOs. Following is a transcript of the video. Sara Silverstein: And what about the ICO bonanza that we've been seeing? How do you feel about initial coin offerings? Ari Paul: I think that one aspect of the cryptocurrency market is a lot like 1999. So, in the early '90s you great high quality projects coming to market. It wasn't viewed as a get-rich-quick scheme to launch a tech company in 1990.
