What holder concentration is and why it matters
How much power a single wallet has over a token's price
What it is, in plain terms
"Holder concentration" measures how much of a token's total supply sits in a handful of wallets, instead of being spread across many different holders. A high value means a few actors control a huge slice of the token.
Whoever holds a huge share of a token (often called a "whale" in crypto slang) has disproportionate power over its price: a single sale from them can crash the value for everyone else, regardless of any intentional wrongdoing.
Why it's a real risk, not just a theoretical one
According to Chainalysis, just 40 whales held 94% of the combined share of the TRUMP and MELANIA tokens launched by the Trump family in January 2025. For MELANIA specifically, the platform Bubblemaps found that nearly 90% of the supply was concentrated in a single wallet.
The risk doesn't even require bad faith: a smaller but direct case, the WhiteWhale token, saw its price crash 60% in a single candle after the largest holder simply decided to sell their share.
How CriptoCheck checks it
We calculate the percentage held by the single largest wallet relative to the token's total supply.
We consider a percentage up to 20% green; beyond that threshold, the check flags red -- not as proof of bad faith, but as a prompt to verify who's really behind that address before buying.
What it does NOT guarantee, to be honest
A high value doesn't automatically mean scam risk: it could be a project treasury contract, a staking pool, or an exchange holding funds on behalf of thousands of different users.
Always verify the wallet's address before drawing alarming conclusions -- the exact same figure can mean very different things depending on who really controls it.
