A very helpful method or strategy for people who have small capital to invest, and many people also do the same as one way to have assets with small capital.
Bitcoin is always the main choice, but this strategy can also be applied to other coins such as the coins mentioned here. many people have succeeded in implementing this strategy, especially for people like us who have small capital.
I'm sure that if we do a survey we will realize that in the forum there are many people entering the world of trading with little capital, few only those who do it with a large capital, few with a medium capital, so these things that we read are very focused on the majority of those who do trading, I started with little capital, I know many who start with 10usd, and it is little, because in trading it is little money, but I say something, if you get to zero quickly you have to keep putting more money there and insist.
Having jumping into trading with little capital though it's a stepping stone in getting to earn something big but at start, your profits will be little; like trading with $10 for instance can fetch you profit of $2 or else your trading on leverage and a trader takes like x25 then you could be making bigger profits but leverage is very risky, as a trader can be liquidated at anytime.
In trading it is obvious that the bigger your capital, the bigger your profits.
Also on investing/holding, you could start with a little amount and likely use the DCA pattern to grow your portfolio as time goes on and a Holder will see his profits on the long run depending on the asset he choose to HODL
