Lunchtime browsing on the blockchain saw a whale address making a big purchase, and someone in the group immediately called for follow-up. I took a sip of cold brew first... Honestly, you need to first think clearly whether they are building a position or opening a short on the other side as insurance. Many big players buy spot and hedge with futures contracts at the same time; their net exposure isn't as large as you think. If you follow in, you become purely naked. Recently, the testnet incentives and points system are also quite addictive; everyone is guessing whether the mainnet will issue tokens, but whales might just be market makers or placeholders, not necessarily true believers. Anyway, now when I see "whale movements," I first look at their overall position changes before deciding whether to act. If I can avoid chasing, I avoid it; I don't want to add drama to myself before sleep.
