I Im in ADA now with 1$ of my capital 3$
I have STARTED now today - anyone knows how to get my poloniex PNL ? So i can show here my PNL
Spot trading with $3 is ridiculous because even if you can make 20% profit from it, it will be only 0.6$ profit. So you cannot earn a big capital by trading with this capital. You can make some profit by gambling with $3 or doing futures training, but you can never get anything good with so little money on the spot. I am not encouraging you to invest high amount. But since you say you have a long experience in trading so I would say increase some amount and then trade then you can earn good profit.
We often recommend to people to use a small amount of money to familiarize themselves with a platform and to test their strategy and verify if it actually works, so it is likely this is what the OP is doing as even if the profits which could be generated with that amount of money are low, they can serve as a proof of concept, so if you could earn for example 40% in a single year with your strategy then the only thing left for you will be to increase your capital until that 40% finally becomes a significant amount of money.
