If I have money then I will invest 70% of my money into bitcoin, but 70% I will not invest at the same time. I will divide the capital to invest. And this is a good time to do this, because bitcoin is currently low.
Depending on the economic situation of each person, but I find that 70% is reasonable, 30% accumulation will make you more secure in the investment, do not invest all existing capital, so will do Make you more worried and affect your investment.
