How can someone buy BCH and think that he is buying BTC is beyond me, considering the huge difference in price. I mean, if you buy BCH thinking that you are actually buying BTC, but discounted for 97% (and not questioning yourself how can that be possible) you will have hard time in crypto. Hell, even on that website they make distinction between those two.
Then again, people are still sending money to BTC doublers, so I guess everything is possible.
They're newbie anyways. The website owners purposedly put the word 'Bitcoin' and 'Cash' together to fool the users. We are not newbies so we are aware of the name difference but a newbie who doesn't have much idea about Bitcoin and cryptocurrencies, they may be confused and thought that's the real Bitcoin. Especially they're buying it on a website which seems 'legitimate' with the domain
bitcoin.com, isn't it easy to be fooled?
