Too risky, if must invest all the savings on cryptocurrency. Unless you are absolutely sure. But, I still think it's not wise. Atleast we have money in savings to deal with sudden and important bad conditions.
You should not invest all your savings into cryptocurrencies because there is always a risk factor involved. Sometimes their is a drop and sometimes their is a rise in price. If their are chances of earning huge profits then their are equal chances of facing loss also. So you should invest some amount of your earnings inorder to get some experience and then you should increase your investments.
