Honestly, my biggest takeaway over the past few years is one sentence: don't let any single position push your emotions to the limit.

Holding spot assets that you can't keep? Mostly because your position size is too heavy, and when it retraces, you start imagining "is this going to zero";
Futures that get liquidated? Even more direct, leverage amplifies the volatility to the point where you can't sleep.
My simple method: first, reduce the total position size, then treat each order as a "possible mistake" attempt, so even if you mess up, you won't need the next trade to turn things around.

Recently, the hype around testnet incentives and points has heated up again, and the group asks every day whether the mainnet will issue tokens...
I usually just watch the lively scene on the side, and if I do participate, I only spend the time and money on what I won't mind losing.
There are many tutorials, but I prefer those that talk about how to survive longer, how not to get blown up by a single needle, rather than flashy entry points.
Anyway, it's okay to go slow, just sit and wait for the candlesticks, and drink tea along the way.
