Siacoin, if it follow prior movement, will fall to our and most likely bounce off one of them. Safe thing to do is buy at demand zones, with a very tight stop loss in case it continues down. That way you won't lose much if it moves down but will be in the game if it starts bull run which can last anywhere from 5 days to 52 days.
I will keep you updated on this trade if you follow me.
