Sniper Bot Tutorial SCAM!!!




 

You can see it everywhere, they even advertise on Facebook, Youtube, Google peddling their scam as "Sniper Bot Tutorial". They will show you how to make more money using Sniper Bot, they will promise you that you will make a lot of ETH or BNB or BTC through simple smart contract deployment.

Here's an example on Youtube:

sniper bot scam




It has more than 30,000 views I hope none of them fell for this scam!

It says that: In this video I show you a simple smart contract deployment in Solidity which automatically locates any liquidity added to a BSC token, immediately buy and sell at profit.

Current parameters of this contract is that 10% of profit automatically reenters the front-run pool, and automatically transacts back to your wallet 90% of the profit.  The remaining pool keeps front running for profit, until you submit "frontrunAction" function in ChainIDE"

It's clearly a scam, who would teach to multiply your 1 BNB to 17 BNB in a few seconds, it's just impossible. “If it's too good to be true, it probably is”

In the video the guy will ask you to go to chainide.com, then you will need to connect your Metamask Wallet. Then go to BNB chain. Then once connected he ask you to make a new file, then you will need to copy the "Sniper Bot scam script" that is provided in the video. Then paste it on the chainIDE. It said that the bot will run on the blockchain and work against the pancakeswap router. He then ask you to compile the bot, then deploy the smart contract to your wallet. It will then ask you to send some fund to the contract asking your to shell out 1.5 BNB that you will never see again. He then run the bot, and show you what he got from the 1.5 BNB which is clearly fake. Don't get scammed! Sniper Bot Tutorial is not true:
