You can start Bitcoin from scratch even with a small deposit. There are some investors who have no income but have a significant amount of assets to invest. How do they invest in Bitcoin or if they really know very little about Bitcoin, how should they start? For such people Bitcoin investment is an opportunity such as those who have inherited wealth they want to use their wealth wisely and become more knowledgeable about their investments. Maybe they are still studying and learning about Bitcoin and have not yet started earning.
But talking about no income I guess that condition will not take them far especially that they don't have any means to buy Bitcoin especially that there's new funds comes to them.
Anyone that has no source of income has no business investing in Bitcoin, what he or she should be doing is looking for a job so that he or she can take care of his basic needs, after that he can evaluate his situation if their is any discretionary income left to start investing with, because for the said fellow to buy and accumulate Bitcoin consistently, he must have an income coming in either weekly or monthly, because if you don't have an income and you invest with the little you have for the time being, it will be just a matter of time before he falls back to his holdings for survival.
You made a very solid point, especially about putting basic needs first and having a steady income before thinking of investing in something like Bitcoin. The truth is, trying to invest without a stable income is risky, and it messes with mindset too. When you don’t have money coming in regularly, any little shake in the market can make you panic because now your survival depends on those investments. That’s a tough and stressful position to be in.
At the end of the day, investing should come from a place of stability, not desperation. It's better to build a foundation first, then grow from there.
