Recently, some regions have been talking about tax increases and tighter compliance.

My first reaction is not "It's going to crash," but: I’ll be overwhelmed come tax season...
In the past, I traded happily, moving funds back and forth between lending pools, and picking up small bits in liquidation waterfalls,
but all the records were scattered across three or four exchanges and two blockchains, with transfer notes still saying "test."
Honestly, what’s really frustrating isn’t the profit or loss, but that you simply can’t explain where that transaction came from or where it went.

I’m pretty old-school now: every time I make a large deposit or withdrawal, cross-chain transfer, or open/close a loan,
I just take a quick screenshot and jot down a line like "Why transfer, to whom,"
don’t think it’s a hassle—you’ll thank yourself at the end of the year.
And don’t expect platforms to always keep complete transaction histories;
if you can export them, export them; if you can save locally, do so...
Anyway, I’d rather do two fewer trades than spend December staring at a bunch of transaction hashes and losing sleep.
