Bitcoin private fork has been under development for quite some time and it is finally happening in 4 days. You can check my previous post with their roadmap here.
This fork will be a Bitcoin/ZClassic fork, which means that you will receive Bitcoin Private for each BTC and ZCL that you own in a 1:1 ratio.
The idea is to bring ZClassic privacy technology into Bitcoin and make it a privacy focused coin.
The date was already announced some time ago but recently there was released a final date on their twitter.
In terms of exchanges supporting this fork, they are working on that and Trade Satoshi was already confirmed as the first one to support it. According to them, the Binance application is on the way and if they make it, that will be a great achievement for this fork.
But besides exchanges, pretty much all the wallets that you control the private key will support the fork.
If you're a more curious person, you can take a look at their white paper. On their tweet, they say "To our knowledge, this is the first Bitcoin hard fork whitepaper.", which is a nice touch from them and I think this should be the way to go.
The point of hard forks should be to bring something new to the technology and therefore should be worth documenting.
And, if after all this your thinking to get some Bitcoin Private from this fork, maybe today is a good day to take a look at that because ZCL is going through a small dip and can be a good entry point. But this is not financial advice, so do your own research first ;)
