As for the QT wallet, I don't use Windows or Mac. Someone will need to build respective versions and release.
Cryptopia's currant block height is 3801642
https://www.cryptopia.co.nz/CoinInfo/?coin=RBBT with eight nodes:
addnode=185.25.60.199:17020
addnode=76.95.178.229:17040
addnode=45.79.186.226:17020
addnode=50.82.94.170:17020
addnode=115.236.88.86:17020
addnode=185.34.14.176:17020
addnode=5.101.122.184:17020
(and they are on version 1000001

)
Unless you find an exchange to take in Rabbit (or get Cryptopia to reactivate a BTC exchange for RBBT), then the coin is dead in the water again.
...and
addnode yields:
{"code":-32601,"message":"Method not found"}so we can't even import nodes on the fly...
