Today 20 April 2018 This is a Good time to Buy Siacoin Because Siacoin Feature is Bright. But Invest at Your own risk.
basically everything is good because every altcoins and Bitcoin were oversold.
(well Bitcoin may go down a little bit,but it won't change the fact that every altcoins were oversold for the past few months).
look at it right now,
everything went up for more than 10% because of Bitcoin,right now Bitcoin started to make its move.
and everybody started to regain their faith on it again.
for a couple months later we may see a 'good' movement on alts,so just hold it until Bitcoin starts its crazy movement again.
