due to the volatility i would only do like 10% or so. with a much more stable price maybe 25% but that's it. 25% at most is more than enough for each kind of investment. rest stays on savings account.
But that volatility is where you can make big profit. The price of bitcoin went up to $1000+ dollars ion late 2013 and there's no reason why it couldn't go there or possibly even higher again. I'd put more than 10% of my savings into it but that's just me.
