The crypto world is the easiest way in today's era to achieve financial freedom now through this the minimum resources required but i think that there are other means also available as in investing in real estate or any other thing the main concept is to invest your money and assets into others things,
In my own opinion, the most unique advise to attain financial freedom is by educating ones self, education is the first key in achieving everyone's goal. Know your plans and priorities, don't focus on how to achieve financial freedom, but rather focus on why you want to achieve it. Life is cruel that you have to work hard for it. Investing in crypto and learning from it would a very nice step to handle and everything will follow.
