now, try in smaller amounts to see how it turns out. SiaCoin is quite low now and might be a profitable investment at the moment, I don't really think it can drop
much more. Altcoins are pretty unstable and highly susceptible in price changes due to high correlation with Bitcoin. A small price drop in Bitcoin, (For example 1%)
will have a far greater drop in an altcoin (Might even be 5%)
Your story is great man, and upon seing the investments you have I think I'll stick to the one I am planning to invest with, and that is stratis coin. It has a higher sell value and after all it gains in the market which you could take the profit sells with bigger amount of btc. So with regards to siacoin it's not bad at all amd all you really need to focus is you should monitor the current graph in order to be updated when price will rise higher.
