I would like to know how 1M is made

Hi. Look above your post.
if you take the time to look at what sells well on the marketplace, it's really easy to make 1mil. Couple that with gathering mats from miner/bot that sell decently, or farming mob drop mats between needing to replenish your selling stock/checking for undercutters, and you're making a hell of a lot.
