After 2 weeks of doing research about this bot.
There are 2 different type of bot.
Snipping bot - This bot will grab the coin, that just got listed - added into liquidity pool as soon as possible. By setting higher gwei to manipulate the mempools.
Grab as many coins at cheaper price as soon as possible, probably at IDO value, and then dump it at public pool at 10x-20x price.
Front-runner bot - From public pool, you can use this bot to grab the coin that already goes 10x-20x dump by snipping bot, as soon as possible, and then dump it for another 2x-5x price.
I knew few people that are selling this bot (snipping), but it's too risky. The bot owner can steal your private keys without you even realize
Unless you're programmer that know what you were doing.
For front runner bot you can use Limitswap. This is legit, you can join their TG group ask the question, guide. But you need to buy their limitswap token, hold it before you can use the bot.
Snipping bot cannot join any new coin that have anti bot system, but if you can, you got the best bot, with the right setting, you can made million overnight.
Front runner bot are immune to anti bot, as they are not bot, they are just another humans in public pools, but faster.
