2:How much money do i need to invest in bitcoin?
The money that you know that you are one hundred percent certain that it is lost to fall in bitcoin price you are emotionally, financially, and physically prepared to deal with it. The range could be from anywhere 3% - 10% of whatever inflow of cash you receive. The word inflow of cash could refer to anything from income, cash gifts, profits on a business etc.
This investment in bitcoin could be every day, week, month, they are not cast in stone therefore the choice is up to you to choose the frequency of your investment. There are people who are raising the bar higher and putting a 100% of their savings into bitcoin. But I got this advice from franky1 yesterday which is worth sharing with you just for you to keep in mind.
keep atleast 1month of income as savings for emergency.. then you will be less panicky to sell investments when life stuff happens or markets change
dont rely on your wealth stash/bitcoin when life gets tough, keep bitcoin investment separate(like a pension you cant touch for years even if your in debt)
