nothing is guaranteed in this life so I disagree with you when you only trading has no guarantee, because even bitcoin investment has no guarantee too, but it is more profitable and less risky than trading, trading is Very risky and it's not really that profitable compared to one long term holding.
Yeah nothing is guaranteed in this life but buying Bitcoin for a long term it’s more profitable imagine investing for like 10 to 15years on Bitcoin I believe your increase is a guarantee by now , that is why we urge people to indulge in investing rather than trading , their is a big risk and lose in trading, trading has no guarantee. New investor should really source for good information and direction so they won’t make mistakes and they should channel their mindset on buying instead of trading as to avoid risk and not making any profit.
