Today I have sent a little Ethereum to my address but it instantly transferred to another address. Later, I tried again sending 0.002 ETH and the same. It also transferred that same address instantly.
How to get solve this?
That is one of the function of smart contract in ETH, you can automate the transaction.
But seems like this is misused by evil peoples to scam other peoples.
Usually they made some address with some token and give private key to public.
Everyone will be tempted to take the token, but need some gas to send the token, then peoples start to send ETH for gas, but the ETH will be sent
to other address immediately. This is clearly a trick to scam peoples.
Perhaps you are right and this is a smile in order to conduct transactions that are very dangerous. But initially, if you are the owner of all these wallets and the funds that are on them, then there are no problems. But if someone else has got access to your wallet and is trying to withdraw funds from there, but for this they need ethereum, then this is his problem if the film is automatically withdrawn from this wallet.
