I want to get started in Crypto buying and selling. What advice can you give me?

I've thrown a few quid here and there in the past at different currencies but purely as a random punt and not with any knowledge or information backing it.

If I were to start with just £100, what can I do to identify good investments, identify best times to buy and sell, help learn about what different markets might do etc?

I've got Binance for the bits I've done in the past, I also know there's a lot that happens on X, Discord, Telegram but don't know what, of all the information available, is seen as the more reliable streams for investors/traders/dabbler's.

What are your top tips for investment? I'm looking to start small while I learn but I'd love to be able to learn how to invest in these markets properly and not just be seeing random nonsense coming through on Instagram of stuff that has no logic behind it.

So Reddit, what can you teach me? Where can I learn?
