I have not been tracking ECA, but from what you have posted it looks interesting. My main concern is the PoS payout rates, but otherwise it looks like a solid coin.
I am going to look in to it further and if the coin is interesting to me I will post about it and let you know, so that you can see what I think of it!
NEBL has a 10% stake rate, 12,690,311 circulating supply and total supply of 13,430,162. Not everyone is staking, but when i posed the question on Telegram no one seemed worried. I agree 50% does sound high and i'm not sure if that level is sustainable. Although, I might be missing something.
Oh okay i see. I'm not sure but I'll have a look and if I figure anything out I'll keep you posted.
