How do you assess a token’s holder concentration?
Before calculating the share held by whales, you should first exclude addresses such as liquidity pools, burn addresses, exchange wallets, and vesting contracts.
Whale addresses can be checked in real time on a block explorer. When whales transfer tokens to an exchange, it’s often seen as a sign they’re preparing to sell, though they may not actually sell.
At launch, $BONK airdropped half of its tokens to the Solana community. It’s currently at 0.0₅305.
Knowledge can help you avoid pitfalls, but it can’t replace position management.

Just my personal perspective; I may not be right, so take this with caution.
