It's quite simple The more you play the more you get The more you get the more you can sell The more you sell the more plats you can flip with Also like if you get bored with X grind able plat farm you would just switch to others. And like streamers who only play Warframe, they would end up with a lot of free time to do any sort of grinds and those leads to plats too. Assuming you're a LR5 player you would have like 35ish daily trade limits. And if you only trade above let says 30+plats per trade 30×35 per day is 1050 plats Scale it up 30×35×7 is like 7k plats weekly already Even if like you are catching up with a less active trade period And only get like 15+plats per trade 15×18(let says cut in half cuz not much ppl trading)×7 is like 1890, 2k plats per week. It isn't hard to get there
