Having the full rights on the technology means that the whole thing is centralized. If you add something that the company does not like, they have all the rights to sue you and prevent you from publishing it. This is usually done for blockchains that aim for internal company use, nothing more than a better secured database. Using this way for a community coin is useless. With such a base there is no difference to any ingame gold in an MMO. Trustless value is not working this way when a central company has all the power.
And don't forget XBY is something unique in crypto space, what they're are doing was never done by any project.
Xtrabytes is a blockchain project running on a bitcoin fork with PoW removed at the moment, nothing else.
It's a temp chain and will be obsolete, after mainnet. Think of this chain as an ERC20 token, before mainnet launch. Read history of XTRABYTES.
It is no ERC20 Token, it is a Bitcoin fork with PoW removed.
