Starting point is a big challenge when it comes to Investment. There are people who find it difficult to start up an investment because what they have is not large. Start your investment with the little you have it will go a long way.
Expectations to have something big to start maybe delayed. Do you know what point you would have reached if you had started with the little which you afford?
If you know how to actually do research and understand market psychology, it's definitely not impossible to hit big with only a starting balance of $20. The cryptocurrency markets is a very very inefficient market. Lots of projects are heavily overpriced, and some are heavily underpriced. You just need to look for the latter and allocate money smartly.
Personally, I've made GREAT picks throughout the years by doing mid term investing, especially this year. I could've still multiplied my money if it's the case that I started with a very low 2-3 digit amount, but having extra money inflow from sigcamps and a small online business definitely boosted my investment capital. And no, I'm no son of a millionaire that started with 4-6 figs.
