First off, don't take anything I say seriously, as this is on opinion basis. That being said, let us get into my insights. 2018, I was pretty confident on Siacoin, and short target-wise, it wasn't that bad. It reached a peak of being in the top 50's, top 30's list for cryptocurrencies. However, Siacoin have went down to #64 and is a dramatically lower price compared to its peak. Yes, the crypto market crashed. However, in comparison it haven't met many market expectations. That being said, Siacoin has potential. People seem to be adopting "Proof of Space" algorithms, and the demand for Siacoin's tech seems to be increasing in that manner. Also, it seems like it does have a potential for a bull run this quarter. It is medium to high risk based off of some of its past performance, but I would say it is closer to medium risk rather then high given the nature of other altcoins out there. Siacoin does have some merits usecase wise, and it doesn't seem to be a bad cryptocurrency or blockchain company. Infact, it is worth being on your watchlist.
