I have bought this service for a month and a Solana minting bot is basically essentially to mint anything that gets signaled. Just about every mint that gets signaled is either in low supply, highly hyped, or both. This is no fault of seoul as hypes like that will usually be the types of drops that can be flipped for the most money. However, if you have a bad bot, bad setup, or no bot you should essentially kiss your chances to mint goodbye as it is a very very low chance you will mint as others will be minting with their own bots.
So essentially it is true that $200 is good starting capital, but you will need an ADDITIONAL $200 to purchase a mid-tier bot to be able to mint.
As for me, I didn't know this information and am now down $100 (though I was able to mint a single signal and quickflip it for +0.1 sol, so that's something)
