Why this grade

One wallet holds 42% of supplyHow much of the coin the single biggest holder owns. If one wallet owns a big slice and sells it all at once, the price can crash.

Top 10 wallets hold 75%How much the ten biggest holders own between them. The more they own, the more a few people can move the price.

Very thin liquidityThe pot of money for swapping is very small, so even small sales can drop the price a lot.
