Normally I never try to catch the first wave because it's simple way more risky than catching the third one.
Siacoin had a lot of negative news the last days which decreased the price more than we expected.
Well it's oversold which normally results in an increasement, however I recommend you to use a stoploss on this trade because its a risky one!
If you're already in siacoin (like I did by mistake) even put in a stoploss, if its catched move on to another coin and let it for what it is.
Be careful on this one ;)
