Is this coin still alive?
Some forgers still active:
https://explorer.horizonplatform.io/?page=graphs&graph=forgers
Has a github repo (just forked to save it for the future):

Exchange? It has a built in asset exchange... It needs only a gateway Asset to NXT AE and it is possible to buy/sell it. It isn't an impossible mission to write a robot
Maybe next week...I started to establish a market for Horizon on the NXT Asset Exchange. I started also to write a robot in node js as a gateway between the blockchains - be patient.
Details can you see below:
1 NHZ (NXT Asset Exchange) = 1 HZ (Horizon blockchain)
Issuer Account: NXT-PTKE-6T4L-YL8W-87B5T (Don't send NHZ back to Issuer!!! A gateway address will be published, if the robot works.)
Asset Id: 14827982687132149115

If you wish support my work (and Horizon) - you can buy already some NHZ on the NXT Asset Exchange - I placed some orders. Withdraw it to the Horizon blockchain not yet works - it needs the working robot - be patient.
If I see - es exists some transacition of NHZ on the NXT Asset Exchange - I plan to contact coinmarketcap.com to correct the price for Horizon.
If you get this to work and keep it active, I'll give you 50M SPD. You are entitled to the giveaway at 1.5x rate at 15M SPD if you cant get it to work for trying.
