Don't expect to scale quickly at all, You'll fail far more than you succeed before know what to bot and what not to bot, when to bot and when not to bot.
Botting long term & ESPECIALLY botting for profit is an investment, long term investment to say the least.
IMO You should
Bot 1 account, get it to last a month.
Bot 1 account, last a month and make profit from it.
Then upscale slowly but don't expect to make $ like it's a printing press. You'll sink money into botting before profiting, thats the key thing to remember
