Nowadays I consider BTC as a pure speculating coin. Because the volatility turns this cripto not suited for being used on daily needs. I think, as investors, we don't have to defend things that our emotions want, but take best decisions on every scenario. All in all, Keep buying it.
Actually "nowadays" (actually for quite some years already) people buy Bitcoin because they've understood its price is bound to rise, hence being a great investment, not because it can be used as a currency, and also sadly not because of its technology or the freedom it offers.
So your logic is badly flawed. But somehow I think you don't care, this seems to be just a new account of somebody having interest in bashing Bitcoin.
