It would be nice if someone propose nicer logo 

[jdwi31]

Do you offer a bounty for logo design?

[passionsurf]

total number of coins?

[tk808]

A lot of these coins are getting really interesting with distribution.

Like the idea, hope i can be of assistance to your development. Pm me.


Cheers and best of luck.

total number of coins?

Not limited. Initial PoW supply not more than 100 000 000

Too bad it's not scrypt-jane 

[physalis]

Too bad it's not scrypt-jane  

I agree. Maybe consider making it scrypt-jane?

Otherwise interesting coin

Maybe consider making it scrypt-jane?

Scrypt seems good today and switch to PoS-only will happen quickly.

I like the new logo rat4

"B" will always be colloding with the B of Bitcoin, but hey, not much to do about that short of changing the name.

jetlee, that logo is also very nice! Not sure about the slogan that goes around it though. What "destiny" does this coin determine?
Also, just from a desing perspective, you might not want to have a text that makes people turn their heads upside down. It's fine for real physical coins that you hold in your hand and can turn around, not so much with coins that are just representations on a computer screen

Stake interest: 1% annually

Is that all?

Are you a banker?

Stake interest: 1% annually

Is that all?

Are you a banker?

Well, nominal interest is 1% annually. And minimal stake age is 8 hours. Now imagine compound interest  

Edited: to be more srs, PoS mining is cheap

Hello,

How is this mixed proof of work / proof of stake working? Could someone give some pointers?
