I added PoS at cryptohub but maximum for staking for one user is 1000

I want to know community's opinion about it

Wow that is great news!
If you want, I can try to optimize the wallet or put in something to reduce CPU usage.
Do you know how exactly works PoS? I was reading that staking has difficulity that depends on summary wallet balance (more balance - lower dif), but how it guess the task? Using CPU? But XLR and WYV wallets currently consume 0% and they are at staking too. Only CROC wallet consumes CPU at my server
When I was looking at PoS code it seems to be nearly random. I think it is myth that "more balance = lower difficulty". What actually happens is there is a probability of a block to be a stake block. You can stake multiple times (lets say, 1000 CROC, staked 10 times = 10,000 CROC staked) to find staked blocks faster. Or you can stake the whole 10,000 CROC once. The payout will be greater, but the chances of finding a stake block will be lower.
My setup is, I'm staking about 10,000 CROC split up 3 times. I make much more this way.
I will checkout the CPU usage issue and make it my priority number 1.
Edit: re-compiling CrocodileCash with -pg to do the profiling with gprof. I'll keep you updated.
