In my opinion changing seed after every bet, it's not good idea. It may slow down the bot and some sites not gonna let you do that. Is there a way to stop it?

The best option would be to let decide player when he wants to change the seed.

Using seuntjie bot, I have function resetseed() and I can use it in script. Something like that:
if wins+losses>100 and wins/losses>1.02 then
resetseed()
end
