here is the facts:
Daytrading makes profit. Ofcourse, otherwise it wouldn't even be there.
I agree that in this stage (early stage in the history of a game) in BB the profit might be too big. But that is a difrent matter. For now, let me explain why we NEED daytrading.
You've explained why we
need market specialists, not why we
need teams making 30 transfers per week, and having rosters larger than can be displayed.
That was the point of my thought exercise. If the DT make the game better, then why wouldn't BB actually hire people to scan the transfer market for bargains and regulate the price?
The alternative is to depend on there being enough DT willing to regularly scan the market for bargains. But is that dependable?
Let's say that I am the equal to another manager in my league as far as tactics, etc. But I'm a little better than him in getting players that I actually use for my team. Both of us get a +4 injury to our star center, so we go to the market. He's in a hurry, and pays $100,000. I have a little bit of time, and am able to log in at various deadlines and so am able to pick up a clone of the player for $70,000. So I am ahead $30,000 of my competitor. Now the day trader is not so clever as I. But he deals in volume. He finds dozens of players for $80,000 and sells them to teams like my leaguemate for $100,000. I could have found the player I bought for $70,000 and bought 4 others for $80,000. But I can't use a team of centers.
The DT can bid $80,000 on 20 players, and wake up in the morning and see what he has won. There is zero cost for bidding on players. There is zero cost for putting players on the market for a fixed mark up, unless you end up paying the salary.
And consider some other possibilities of cost-less trading. You have scouted your opponent and sees that he likes to go inside and you prepare accordingly. Meanwhile he buys 3 3-point bombers plus some passers and your 2-3 zone simply provides more hands to in-bound the ball after the shot is made. He can sell either the 3-point bombers after the game, or perhaps his centers.
I can't use more than 5 players on the court. I can only train 4-6 players. I can't expand my stadium to twice what I can fill. I can't play more than one scrimmage per week. I can only hire one coach, doctor, and PR guy. But I can trade dozens of players per week. That is the problem. It is the volume.
