I had 9m+ sentient at the beginning of this week.Now thats great logic ...
The only player I am aware of that posted on the forums is MichaelMichael and after many called him out for his trading activities he stopped posting.
ok at 60 per swipe that implies almost 17 sets of trades... OK I will give you that.
So I will ask the most important question where do they get these MILLIONS upon MILLIONS of Sentient goods to trade that nobody else seems to have? And no they dont produce them I have looked many times
But to give you a better answer, pretend you sell 20K sentient for 22500 sentient.
60*20.000= 1.2M sentient.
Each cycle of goods delivers you 1.350.000 sentient
Profit per 60 trades = 150K sentient.
So you do not need that much sentient, and the profits are pretty decent, so even if you start with 300K and only 15 trades, it doesn't take that long to get to 1.2M at which you are fit to go all out on trading.
So while you might trade many millions of sentient a day, the maximum amount you need is actually little, you just cycle the same goods over and over and over again, because with each trade you get your money back + a profit.
