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!
Yes it is very risky to invest here in bitcoin but if youll choose an ICO that you think is trusted dont hesitate to invest because it is really good to invest here in bitcoin because as you can see the price of bitcoin as of now it is really rising and reaching the high amount that is very interesting.
