I like Siacoin because when I bought it, it was about half the price it was now. However, I HODL'd too long and missed the opportunity to sale it right before the big "crash". That being said, Siacoin is likely to have a small positive correlation trend again and could even be a dip when it reaches a twenty cent price. Overall though, I would say they are a high investment risk. Given what they are doing with Siafunds as well as market potential, I would still recommend it as an investment (even if I was wrong with a few correlations in the past regarding them).
