Obviously these people are investing in bitcoin behind the scenes, but what they are saying is not completely out of proportion.
You see, bitcoin core developers treat it as an investment, as the digital gold, not as a payment method, that's why Bitcoin Cash was created in the first place,however, like everything else with no real usability, it will raise so much until it crashes.
Bitcoin fees are touching the sky, confirmations are taking a long time for a lot of people, no anonymity whatsoever, why not just use regular money then?
PS: I'm a Forex, Binary Options and Cryptocurrencies trader and I have made a few thousands solely because of BTC price increase, I have been following it since the beggining, so mark my words, people WILL lose interest in BTC and it won't take that long.
If you are smart and let your feelings aside, you will make a good profit in the upcoming months of this bubble and know when its time to quit.
