That's very risky. Let me elaborate, BTC market is still very volatile, therefore can suffer a lot of ups and downs. And suppose you need that money, but suddenly the BTC price got down, and you no longer have that same value, you will be at loss there. I thing you should invest some of that money sitting in the bank, and leave another in the bank. This way you will have money in case of need, and you can let your BTC converted money increase in value throughout months!
