I was randomly moving across Telegram when I stumbled on this scammer who asks for subscription from unsuspecting users to give them access to searching the blockchain for forgotten wallets. This is a scam channel because you cannot obtain seed phrases from the blockchain, they are generated by your cryptocurrency wallet locally, the blockchain only stores your public addresses and your transaction history, so there is no way any wallet can be obtained by scanning the blockchain, seed phrases are set of 12 to 24 words that can be used to reconfigure a wallet and give you access to addresses of coins stored on the blockchain.
Searching for a forgotten wallet on the blockchain ? That alone is incredibly strange, let alone the scammer trying to sell it to potential victims. Just by using basic logic, how could someone sell such valuable (in reality; not) information to others ? So, when you already understand that using such basic logic, you already know it is a scam.
Well, I think this scam will be easy for someone without a basic understanding of crypto, or someone who is easily fooled by things that seem "Too Good to be True". So, I hope you don't fall for any scams, try to be skeptical of any information you find, and verify its veracity. Even wiser, you should simply ignore any information that seems strange, or offers something that doesn't make sense.
