But I want to know what the biggest risk is to hold Bitcoin?
For me the risk of investing in bitcoins is their price, maybe you're holding it for top long that will come to the point that your money will be worth nothing. But that will only happen if and only if the value of bitcoins will drop and will totally fall. And we all know that it will not happen because a lot of big people are in to thia stuff and they will not let their money go to nothing. So the second risk is it might get hacked if their will be a very great hacker that will hack you wallet so bitcoins will not have liabilities to that if that happens. And also the price is not stable so if you hold your bitcoins and spmething happens then it falls and when you needed the money, you will probably cut your loss and thats awful
The only risk which the people fear the most is price volatility but price volatility is a part of business because investing in bitcoin is a coin business and you should dare to invest money in bitcoin if you want to earn money in a short time and with ease but sometime the conditions are not in favor.
