I believe theres always the desire to get a stable source of income after retirement and this may be realised through setting up businesses with money earned from crypto. You will need to further manage these businesses well so I think the money may not be from passive source.
For the next 5 years , I want to be a debt free and earn a passive income. I have to pay all my debts and to start saving by investing or build my dream business. To have a better life for my family specially my parents and to my future family. I want to retire as early before 40s and travel.
