I'll save 5 BTC in the form of fiat and 5 BTC for investment.
why do I save most, because it's a savings, if something happens to my investment
yeah a lot of people say that do not use all your money to invest. because every investment have risk of loss. you certainly do not want to if all your money is lost because of the investment right ? so do not use all your money to invest dude maybe use a few percent only
Yeah, as there was a saying that "don't put all your eggs in one basket". Just invest what you can also afford to lose. Not all investments will gain sure profits. Others will pay you at first but will eventually become a scam before you reach your ROI. Study first where you invest and make sure that their company has a good review that your money won't be wasted.
