Not all but I have invested 50% of my total funds in bitcoin as I think it has a great ability to rise in future which can give me 100% return on my investments which may not be possible with any other form of investments.
What is the price of bitcoin when you invested 50% of your fund? For sure you are able to make it double already or even I'm thinking that you are able to make higher right now. As the price is pumping you should be getting more than 100%, and there are a lot of people here that are getting higher percentage of their profit.
He started investing in bitcoin in may 2 and i think it is not enough for him to gain 200% of his capital because bitcoin is just starting to go up, If the price of bitcoin reach up to $2,000 then he can easily double his money and or even tripled it if he continue to hold bitcoin for long term.
Where did he said that he started to invest in bitcoin yesterday? If he is still new to bitcoin, he needs to wait for a longer time before to make his investments grow up to 200%. But it's a good choice that he did put 50% of his total wealth to bitcoin. He's the one that will get the benefit on it because of bitcoin's rapid growth.
