Is there some kind of universal law that says: "bitcoin will be worth more than $140"? I don't get this kind of advice. Maybe I have been here for too long. I saw the price fall 50% in one day many many times now. I also saw bitcoin lose more than 10 times its value in just a few months. Putting 1/3 of your money into bitcoin and sitting on it means that you might lose half of that tomorrow. You can also double it, I have also seen that. Anyway, this is speculation. It isn't a perfectly safe and lucrative investment.
