The SpecialCoins Ecosystem consists of three different cryptocurrencies with three different functions and accessibility to three different audiences and markets.
Each coin has a cutting edge and unique feature set. In addition to unique SpecialCoins coding strengths and features, the lead community developer, Advisor, is able to examine and improve the code of other projects to incorporate into the SpecialCoins Ecosystem.
In this way, SpecialCoins not only have the best of what is generally available in other coins, SpecialCoins also have features, improvements, and tweaks that are not available in any other project.

Our Mission

Bitcoin heralded the coming of cryptocurrency and is still the most visible.
However, all know that the future will be in altcoins.
The SpecialCoins ecosystem is positioned to be designed for the user needs.
To offer user friendly experience, aiming for widespread adoption by beeing flexible and adaptive.
Diverse feature set that ensures the GravityCoin, BitcoinCZ, and BitcoinZero will be the choice of the global population, when the world is finally ready to embrace cryptocurrency for real commerce, real usage, and real store of value.

BCZ Masternode Setup Guide in 7 simple steps.

Nodes are computers that host a full copy of BCZ’s blockchain and help to verify the validity of transactions.
Masternodes are a special type of node that earn a part of BCZ’s block reward (currently at 1.0 BCZ of the 3.1 BCZ block reward ) in return for hosting a reliable and powerful node that helps to support the network. Masternodes require a refundable collateral of 5000 BCZ to ensure masternode holders have a stake in the coin and are incentivised to keep it working honestly, updated often and have a high uptime.

If you expect the possibility and desire to install masternodes, follow the link below for complete instructions
