Some tipps for a fresh beginner?

Hello everyone, I just joined the community and wanted to know what in your opinion I should look out for, when's the best time to buy or sell, etc. Just some general remarks regarding dealing with crypto.

I know it's a bear market right now and I started by investing a whole 100$ into it just to get the feels for the market, etc. I also have mouths to feed so I'm reluctant to throw in thousands in this regard before I don't feel confident about it.

Currently I split the 100$ by buying some Doge, Algogrand, Aergo, Polka Dot, Amp, Polygon, Solana, Litecoin, Bitcoin, and the usual ones that Coinbase gave me after learning about Sandbox and The Graph.

Furthermore, what's the typical period of holding and what is the typical times or days that have the most volume traded?

I am not new in financial investment or portfolios, I am just new to crypto because well the bear is a good sign for buyers.

If you have anything that'll help me find a better routine with crypto, please let me know.
