I just saw someone on the blockchain chasing after "whale addresses" to copy their moves.

Honestly, I want to advise: don't rush to follow, and distinguish whether they are slowly building a position or opening hedges elsewhere to cover risks...
Buying aggressively from the same address doesn't necessarily mean "bullish"; sometimes it's just moving positions from A to B, or locking in the direction with perpetuals.
To put it simply, we only see the whirlpool on the surface; how the tea leaves are stirred underneath is uncertain.
By the way, I’ve been thinking about the recent social mining and fan token schemes—"attention is mining."
It's lively, but attention can also be used to dump assets.
Focusing on likes and shares can be pretty risky and addictive.
As for that idea of "following whales guarantees victory"... I’ll just laugh first.
