50-80k per day is easy possible. The only important thing is that you are looking for the right players.
some hints:
1. check on
You must login or register to view this content. how many trades per day are made, a player with only 5 trades is not worth to search for
2. usually you can make bigger profits on non-rare players because noobs who don't know the players will sell them at around 400-1000 instead of the market price of 2000-4000. (even happened to myself, yep, I don't know all the players and I sold a unrare gold I had in a goldpack for 400 instead of 3000 because I had no clue that he's popular)
3. Based on my experience, most deals I made with the autobuyer were between 5pm and 11pm. It's probably the time where the most players are online and therefore the most players sold.
4. Based on my experience, the best configuration for the autobuyer are 3 players with a delay of 3500ms
Usually I'm looking for 3k unrare gold players. I get them mostly at around 500-2000. Means approximately 1000 per deal. I turn on my autobuyer everyday between 3pm and 12pm and usually it buys 6-8 players per hour. --> 6*9*1000= 50'000 coins. Sometimes I'm lucky and it's even up to 80'000.
