My bet here is: Some guys could make a community to donate to this address and the first one that collects it will be the rewarded, its like a burn BTC address but instead it will reward any random individual worldwide. it could be a powerfull entertainment.
Most of the people who publicly post the private key are scammers who program high-speed bots that withdraw money once deposited, but this scam activity is in altcoins.
The idea is simple is to put an amount of tokens, for example, 500 USDT and put the ether address in addition to the private key.
- You are now asking the person to send $20 to that address and send him the private key as a guarantee.
- Once the person makes the deposit, you have a high-speed bot that automatically withdraws that money to another address you own.
In Bitcoin, it's different
What you are trying to do is compete with who will broadcast the transaction first from that address and by doing some computation and a bit of luck you will be able to broadcast the transaction first regardless of how quickly the private key is accessed.
In general, do not try cases of quick or guaranteed profit because it may be an indirect scam.
