Is this the newest version for Bitcoin Z wallet?
https://github.com/btcz/bitcoinz/releases/tag/2.0.6

How about the size of storage space to download the full blockchain data base of Bitcoin Z? I don't want to install it if it needs big data space.

After 4 years, Crex24 and STEX are still the most friendly and biggest exchanges for Bitcoin Z according to market history data from coinmarketcap. So do the Bitcoin Z team have tried to contact more exchanges to list the BTCZ?
