interesting coin, fair start!
"PoS interest: 10% per year" - seeems not very much to me, in comparison to other pos coins.
how can you be sure to provide good network security with this?
10 % POS is enough to keep initiative to stake coins. Network Security is fine. I can see 15 active connections in wallet . (POS diff. is strong)
It also ensures minimal inflation. Only around 2000 new BTD coins are generated per day. (good for BTD value)
