$BNB , $SOL , $NEIRO

I want advice from experienced people

- After verifying my account on Binance, I entered with a few dollars and made some trades in spot trading, but I did not succeed in them. I do not know what the problem is; is it in setting limits or what? I had to cancel them after a long wait.

- I returned to the method of currency conversion, but here too I faced difficulties. I was monitoring price movements using RSI and candlesticks and then acquiring currencies that are declining in value.

- Now I hold values from NEIRO, SOL, BNB, in addition to small parts of other currencies, and I am committed to holding them until they generate profits.

So please advise me:

What should I do, how do I choose the right time, and how do I set the limits?

Thanks to everyone who contributes their advice and opinion to teach us trading techniques.
