I think you should go big or go home . So 100% of your savings is good. There is no problem with it. Good choice.
Investing all our saving is so risky but may give you so great income as well, "go big or go home" that's nice saying but only for risk taker who are ready to lose all they have. If you are not ready to lose all then do it, but if you are ready then GO for it.
I my self will not do it ever, prefer to be safe than sorry.
