I suggest you invest 50%. It is too risky to invest all your savings in cryptocurrency because the future is unpredictable. Invest what you can afford to lose.
It will be wise because investing all of your saving is risky if you are not a well experienced with bitcoin, I really believe in investing half of your saving because this way if you will be in some emergency need of money then you will not have to use your bitcoin. At very start should start with spending less and earning high and gradually you will become experienced and get a lot of benefit. Money is not easy to earn so just be careful.
