Good article by Ray Dillinger about the current state of cryptocurrency and ICOs. Ray was involved in code review and security auditing of the block chain portion of the Bitcoin source code for Satoshi Nakamoto. Interesting to read a little about that history too.
Two things brought up that are really worth paying attention to:
The author lays out some ground rules for doing due diligence if buying in. If you're not following the guidelines mentioned at least acknowledge you're being a fool as you part with your money.
The second thing is more interesting to those creating ICOs. He mentions some of the similar digital currencies created before bitcoin and how people ended up in prison. He notes how many of the current ICOs are following the same path. At least take the time to read so you know where your heading.
