what about capping investment amount?
max.bet is rarely used anyways and it´s sad to see my share in the bankroll getting diluted
more and more every day

(i know that is not gonna happen, but I needed some place to whine about
my low percentage of the site bankroll)

Bad idea and also impossible. Would just force users to have alt-accounts
I think he means to limit it as for example, BR cannot exceed 10k BTC (for instance).
It will not happen. More the better

You never know how every whale wants to play anyways!
yeah i meant this

but at current size of bankroll it´s just impossible to gain enough to make this worthwhile.
therefore all the profit goes to the same 20-30 people wo have invested 50+ BTC or more.
i mean in order to have only 1/100 of the bankroll you already have to invest 72 Bitcoin.
but I know that this is not gonna happen, just needed a place for my rant

JD had a ~50k bankroll and I still made a fairly decent return in the ~6 months. It's not the size of the bankroll that matters, but the ratio of wagered vs bankroll. In JD it was 100:1 IIRC. In DB it's only 4:1 so far and rising, so I think we are going in the right direction. Also keep in mind that larger % of bankroll can go against you as well. I have investments in some smaller bankrolls and have been down as much as 10%.
