Some people predicted that SiaCoin will hit around $1 before this year ends but personally I don't it's possible because their crypto project as one of the online file storage isn't that impressive.
SiaCoin was lying for around $0.02 for a long time but that doesn't mean it will surge it's price when Bitcoin and Ethereum will pump.
SiaCoin as I think will stay on it's current price value for a couple of years and investors should divert their SiaCoin asset into another promising altcoins available in the crypto market today like Oyster Pearl.
