There should be nothing to worry about here. John would say whatever he likes to say though and as a matter of fact, he seemed to be sincere about all of the negativity that he spreads about bitcoin. I've been hodling bitcoin since early 2017 and had already profited a lot from it, even so, I am still open about the idea of something else that will take over it. In my honest opinion, BCH, XRP, and LTC serve the purpose better than BTC. Be that as it may, BTC might not be a shit coin after all.
