XtraBytes can not be forked since there is no blockchain to be forked. Talking about copying their tech is just a ridiculous discussion without any base. They have a website, a client and that's it. As long as there is no blockchain, this is not even a blockchain project. Let's take a look at the facts for the moment:
The main developer is an anonymous guy with no verifiable experience in blockchain development promising having invented a revolutionary technology but no one has seen the code yet. Its publication has been delayed several times for months now.
The whole team is more or less anonymous as you can see on the so called "team" site. The team itself has not seen the code.
People working on this project are paid in XFUEL, a token created on the not existing blockchain out of thin air. The hype they make might be because of wanting to trade their worthless XFUEL for XBY at the moment. You can see on their discord that many developers try to get rid of their XFUEL.
All news you will find are unrelated to the blockchain itself. It is all about a new website or a client but you will not see anything related to the revolutionary blockchain itself.
Even the lawyers who are being said to be working with the developer on the patent are anonymous and therefor can not verify this project.
The thread on Bitointalk forum has been closed to stop the critics. People complaining about these things get banned on their subreddit and discord.
It is said to be a community coin but in fact the patent will make a fork impossible and therefor this is not going to be controllable by the community.
There is not even a message from the lead developer for months. He just disappeared as well as his partner.
Take a look at the GitHub of the blockchain:
https://github.com/XTRABYTES/XTRABYTES No changes for months except the readme file.
What happens next? Fanboys, XBY accounts and so on will try to distract from these facts by calling this FUD, bringing doubtable facts about any kind of conspiracy against the XBY project but they will not have any kind of arguments to refure the above facts. Just read about the project, it is always exactly this way. But it is impossible for them to give any other reaction because of being completely empty handed.
