There is no cryptocurrency that cannot be used for trading purposes its just a matter of having the necessary skills to trade the financial markets.
Trading is not just a thing that anyone can do, it takes learning, knowledge and a lot of practice to master it, when you master the art of trading, you can trade any financial instrument
I agree that all crypto can indeed be used for trading, but the problem is not everyone can make profit from trading. It takes knowledge
and experience to be successful when trading, so we need to learn first to be able to analyze crypto price movements in the market.
After that, start trading with a small capital, if it is successful, we can slowly increase our capital. As long as we have a strong will,
there is always a way. The conclusion is that Dogecoin can be used for trading, it doesn't have to be holding Dogecoin to make a profit.
