which strategy works with little money?

none.

keep monitoring the cryptos and seeing the news in the defi infrastructure. You need to have at least 10USDT in each asset to be able to trade without worrying about high fluctuations. Other than that, little money is only good for wasting on altcoins or testing your luck.

but I will give you a heads up:

combine the 10USDT in each asset you are targeting, if you profit ≈3%, sell. If you have 10 assets, you will have 30USDT in profit and can target more assets. This variation is a normal fluctuation that won't harm you if the whales decide to make their investments.

Remember that you have little knowledge, being imperceptible to the orders in the book is the smartest thing to do.

That said, I continue to monitor the cryptos and resume my defi studies.
