The main challenge that I see with a Small capital investors are to maintain their capital because investing it is really hard to choose wether it will grow or not in the currency they invested. And I think most of the time they always lose some of their investments because of lack of chance in choosing the good currency to invest.
You are right, small capital are hard to get more profit and chances are very small compared to those who have big capitals. And It is really hard to avoid loss in investments too.
Actually its not a good idea to invest if you have a small capital and dont have the knowledge to do it. Its better to have a good normal income first like from salary or business or even bounty campaign in crypto.
But if you already have the knowledge of investment, it doesnt matter how much you start with.
besides the benefits obtained are smaller than spending large capital if we make an investment, indeed it would be nice to collect the capital that we have in advance to start investing and do further understanding so that we can understand the risks that will be faced
