Then Bc is a Bitcoin clone!? Or is written from scratch?
Pure POS part was writen probably from scratch
we don't have any other working coin without POW disabled.that's not true

just search around

If there's no mining in NXT, how exactly did the coins get distributed? Someone mentioned that people bought them initially. So the developer made BTC off of selling his premined coins? At least ripple gave some away for free...

Both these coins seem shady. 100% POS ensures the whales get richer.
i was nxt stakeholder and i say that nxt is a total scam considering the initial repartition.
bc was more fairly distributed, only 7 days, but people had a fair time to buy it when it was cheap. i bought bc early at 2500 sat and saw it go down to 500 sat without much fear

i'm waiting for a decent nxt clone to buy in, and i have a nice stake in bc for long term.
Anyway every markets are fucked up right now due to this little chinese crisis :p so i'm buyin cheap alts
you mean Nxt when we were buying Nxt in November for 100 Satoshi? Or in December for 400-2000 Satoshi? Now you can buy for 5000 Satoshi
