What I found is this posting on Telegram from an admin of the Coinsbit Telegram group. There a low quality video is linked in 240 p. I was falling several times asleep when Nataly Simson finally started to talk about “BTCU” at 16 min 28 sec. Indeed she seems to be part of the game (well, I stopped the video a few seconds later).

So I summarize: You're notifying about the idea of your “coin”, which you haven't gotten to run practical ever. Therefore you want to make a “fork” of the SHA 256 encoded Bitcoin blockchain (for which reason ever) and building a new blockchain with the Quark algorithm (together with a mix of other algorithms) on top of the SHA 256 encoded part from the previous Bitcoin chain.

I still have no idea about the real goal of the whole theater, but it's clear that you're selling unlaid eggs, dreaming from the reinvention of the wheel and therefore trying to plant a cactus on a sawn-off tree stump. It's simply ridiculous and the whole thing was for sure the worst advertisement for the Estonian trading platform Coinsbit. Most likely you just want to manipulate the market and stir up the Bitcoin trades on your trading platform in initiating an hype. This is exactly the way how the market is being manipulated. I stand by my assessment of a fake campaign! I really wish you all the luck in the world, but please not in the crypto area!
