For me, this is kind of a huge investment, but should I actually do it?
What are the risks of doing this?
Yes, it is huge investments for me too, if it is idle money you must do it.
Because if you just put your whealty in fiat money the values will be taken by inflation
not only investments in bitcoin but all of instrument of investments are huge risk losing money.
Putting that huge amount of money in bitcoin will help him to earn money without doing anything because even he just stock his bitcoins in his wallet, he can still earn money because the price is so volatile and it almost goes up every time. Investing in bitcoin doesn't mean that it has a huge risk of losing money because if you are a true bitcoin believer and you do a lot of research about bitcoin, you will realize that bitcoin is one of the hottest and safest investment.
