If you receive suspicious coins or NFTs, there is a strong possibility they are scams, but don't panic. The tokens can't hurt you just by sitting in your wallet.
The scam works like this. Scammers send you NFTs that look like free airdrops or giveaways in hopes that the allure of free money will entice the unsuspecting wallet owner to try to claim the reward. These tokens often have a website written on them, like this:
If someone connects their wallet to this fake reward website, no reward will materialize, and instead, the smart contract will drain their wallet.
But remember, you'll be safe if you don't interact with the website. You can keep the tokens in your wallet or send them to another wallet without risking losing your crypto.
Not every token you receive is a scam, however. A few are legit airdrops from projects trying to drum up publicity, like Seal Wif Hat. Most will never be worth anything, but a few manage to appreciate in value. Bonk was first distributed as an airdrop in December 2022, and when it appeared in people's wallets, most had no idea what it was.
So, what should you do with suspicious tokens?
Solana wallets have added many features to help you manage spam tokens. They enable you to hide or burn them. Sol Spotlight recommends that you hide most spam tokens and only burn the ones you are 110% sure are scams.
If you can't figure out how to burn spam tokens in your wallet, you can use Sol Incinerator.
