[...] as the user bob123 that have no idea how market works [...]
Then, please explain it to me.
Especially this:
1. More bots running the trade equals more support for the trade which equals to even higher probability of success.
How can it be more profitable for an individual if more people use the exact same strategy and make the same trades at the same time?

So i simply refuse to spend an hour setting a vps and the time to manage it for a guy that has a 50$ bankroll and when we lose 5% freaks out.
Why do you need to set up an own VPS for each customer ?
They don't have access to your bot anyway.. so why not just run multiple instances on one VPS ?

Just seems to be an excuse.. But feel free to proof me wrong.
