Because earning process is very fast.
I made that now 20% of investments are on "earning" status, instead of 10%
No you should not, this will again slow down the game, this earning 10% or 20% never helps just delays the game which in turn delays reinvestment. Its upto you though but take a poll on this. It should not be more than 5%
I have never seen people withdrawing their investment before they reach 2x or 1.1x so there is no use of giving earning to 10 or 20 % people. There maybe very few exceptions who withdraw before but they are 1 in 100
The problem is that if there is only 50 investments confirmed, this means 5 are earning, and then if a big investment like 1-2 BTC comes, all 5 ends at time, and remaining amount must be distributed again to new 5 invesments, that perhaps also end at time, and again this process is repeated many times.
so it is better at least when there is few investments in the queue, to have more invesments earning.
