Siacoin is famous for 90-100% retracement
we should expect it to drop more and to 40-50 range satoshi
This is not the time to buy alts but wait for them to drop massively.
if you trade coins with only mind , you will be burnt.
Always use the eye of third party who don't buy or sell the coin to look at the chart :)).
