well the risk depends on the amount you put in like in anything, my estimation is that within 1 month it on average moves around 10%
You are right, All of risk depend on the amount you put it. By the way, I think investment in bitcoin is not too risky. because, In a long term, bitcoin is a profitable investment. So we don't worry how much we invest in bitcoin.
The risk factor comes into effect if you are not entering at the right price,as an investor your never spend time and money by entering the bull market at its peak and if you are able to study the price range and the price manipulation then you will understand what a price should be if you are looking for a profitable investment.
