What do you mean fake?
The video is quite basic, can this be manipulated into showing a certain balance which doesn't exist in reality on that site? Yes its not that hard to do and putting in the effort to alter the moving picture to reflect details incorrectly is worth doing if it inspires confidence in your potential clientele. Its a steady industry and some of us are better acquainted with the legion of scammers then others, I've met people who have constructed the most beautiful seemingly intricate websites that appeared to be an actual real casino filled with hundreds of people talking but it was all a false projection to convince me I should engage in the legitimate transaction of passing money to this person.
Its so common, it happens perhaps hundreds of times a day this kind of scam and the only thing slowing people down is reaching out to new 'customers' to convince them of this marvelous money producing scheme. All you need to do is send them an irreversible transaction.
If you want to tempt fate and be a troll you could offer them a credit card payment, they wont be as keen because this is reversible. I would not advise you to actually do any real payment detail for a joke or not but if you test their reaction you might notice they dont like anything that would be reversed on fraud. BTC is great but its also powerful in having no reverse or governing body, its for a good reason but the scammers favour this method and you as a user must be on your guard.Feel free to give us screenshots if contacted, there are lots of people on this forum who have experience and can be useful to point out how common this technique is and I hope you gain from that experience and avoid the idiots and their cheap tactics. I dont advise talking to anyone suspicious tbh, not directly as they will have a variety of techniques and deceptive methods to target you with; scamming industry is actually very large and active.
I believe Application could be built on top Bitcoin to reverse transactions though. If such application already exist, buyers could ask the seller in the video to use it as a safeguard. If the buyers notice the product is scam, they could get the application community members or arbiters to reverse the transactions.
I believe everything credit/debit card does can be easily done on Bitcoin
without necessarily compromising on Bitcoin standards
