I knew that it should be a downside of those Frontrunners bots.
After watching closely, just saw a Bot losing 18.1 ETH ($12,000) in one second
in the same block, and another 13.4 ETH ($8900).
The thing happened today Saturday 19 Dec 2020 @ 19:50 CET.
The bot placed a very big order to buy a Token named Freeway (FWT).
Bot address on Etherscan

The Bot bought 6.2 Million Coin for 57.2 ETH
The bot sold them the same quantity of coins in the same block #11485424 for 39.1 ETH what
lead to an 18.1 ETH Loss ($12000)

The Story didn't stop here,
The Bot continues it's a mistake (Because it's a bot daa) and Buy again Saturday 19 Dec 2020 @ 19:52 CET,
the same Coin with 39.1 ETH and sold them same quantity in the same block for 25.66 ETH what leads to another
loss of 13.4 ETH ($8900).

In the end, the bot loses $20,900 in 2min with four trades.
I was pretty sure at one point those frontrunners have a downside, maybe they deserve we don't know.
