NFT Rarity Check - Moonrank and Opensea issue

There are several sites to check Solana NFT rarity.
I have used MOONRANK to see any NFT rarity.

Moonrank

Not always Rarity directly link to price while every rarity sites may have different standard to rank NFT in rarity.
But it would be helpful to know real value of my NFT and set a plan how to liquidate my NFTs or buy relatively more valuable ones.

And recently Opensea try to take much portion of fast growing Solana NFT market.
But I highly recommend you all not to use Opensea to trade Solana NFT.
One of big strong point of Solana is its very sincere development team and investors. So, if there are any issue happen on protocol or newly launched service, most of development teams try to fix and cooperate each other very fast and smoothly.
In this dimension, most of protocols and services cooperate each other to cheer up its Solana community and to be matured technically and financially.

Recently one NFT project found its fake NFTs in Opensea, so try to communicate with Opensea to ban the NFTs trading, but no response at all from Opensea. So it made much damage to investors for the fake ones.

If you want to buy Solana NFTs, it would be good to use Magic Eden, Raydium, Solanart, Exchage.art etc.
