is it risky to turn all my money to bitcoins? anyhow this money sits in the bank and do nothing for!
Its highly risky. There is no set laws in any country related to it. Moreover its heck of volatile. So investing all your money in bitcoin is going to give you a lot of heart shocks each day. But yes invest 30-40% of your money for long term.
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!
The fear of taking a risk is very risky. If you are always afraid of taking a risk then you will never make anything good for yourself. If you are afraid of losing all your money on bitcoin investment then why not do 50-50 of your total asset? For me, I always go with all of my assets. I'm still young, so what if I lose all of my money? I can still start over in no any time and make something for myself. I just have to be right one time and retired for life.
