Trading tips for beginners?

Good morning all of you most excellent degens!

It's the bear market … research, yes yes, but also the time to learn trading and mess around with small amounts and get a feel for things. Looks like the best time to learn as it's gonna be relatively slow going for a while …

I'd be grateful for tips from old salts (I've only been in for 18 months) that don't entail 'don't trade, just HODL'. Looking at basically messing around with shorts/longs and a bit of leverage out in DeFi land (GMX as a starting point) … anyone got any vibes on this approach?

Fire at will – and thanks in advance.
