Recently, the narrative around parallel processing and sharding has become popular again, with more people incentivized on testnets and earning points, and daily guesses in the group chat about whether the mainnet will issue tokens.

While it's lively, I personally focus more on two things: where to store assets to be safer, and whether the route is accessible when I really need to withdraw (bridges, withdrawals, NFT order book depth, etc., all need to be checked).
To put it simply, don’t let the words “early participation” rush you into panic; I see myself more as practicing now: practicing not to chase highs, practicing to think about exit routes before confirming, practicing to step back when I see large order walls change.
Aesthetics can be online, but don’t treat positions as faith, just start with this.
