When I first came to the crypto world I start with only a laptop. This was all I have and I made a good amount of money because of the last bull season. But because of poor money management and lack of experience, I took a big amount of loss too. I do make some losses but the lesson learned is priceless.
1. Money management is very important. It is better to have some plan than no plan.
2. Opportunity will come again and again so do not FOMO.
3. Anything could go to zero no matter how big the project is(Luna disaster).
Now I know how cash circulates into the crypto markets. I know fundamentals are the most important part of a project. I again could do mistakes in the next bull season but I will be more mature than to handle the situation. I do take some losses but the lesson it gave me would save a hell lot of money in the future.
The two big things that did it for me, were being lucky enough to get up to a decent salary by falling into the right line of work and also doing a lot of research into money management which is your first point. It is very true that "it takes money to make money", what you'll find with a lot of people who started with very little is that they built up their fortunes brick by brick over a long time - it's not a case of trying to find a short cut to suddenly become wealthy, that happens to the tiny minority. You're better off sticking the vast majority of your money in a global index fund which tracks companies of all sizes and be happy with the return of 5-8% you can expect to get on average from the profits of all those companies.
