These (scammers) use blockchain for fraud, this is their aim. This is reality...
Looked at the website, it seems that every man in the world is sending Ethereum here
I was surprised why sending in such a huge amount? I did not know what this thing is because there will be a concept. Then I came to know that if someone sends 9 Ether, he will get 97 or more back. Means more than double
But nothing has ever happened nor will it happen, When you scan that wallet on etherscan, you will see something like this
You do not get any transfer history on the Ethereum blockchain. And it is written here that this is the hacker's wallet address (fish/hack)
You check it yourself:
Wallet: https://etherscan.io/address/0x97d3BFeeD43db559bFF64f8192f2052C7267656a
