Obviously Bitcoin price; the amount Bitcoin is worth at a particular time, and Bitcoin usage; the rate at which Bitcoin is adopted and used. The above phenoms surely has implications, one may be tempted to as; which is more important? The interesting fact is, price affects usage both positively and negatively. An increase in price attracts high usage, and vice versa. Conversely usage also affects the long term pricing of Bitcoin. Price has short term implications, usage and acceptance has long term implications. From the aformentioned, I can conclusively say; Price and Usage are phenoms that can influence the volatility of Bitcoin
I would say that increment in price doesn't attract those people who want to make Bitcoin payments but it definitely attracts people who want to buy it and keep it in their wallet. Price increment on its own doesn't attract people to make transactions because it's making transactions more expensive. If 1 sat/vByte fee worth $0.08 today, after the 100% rise of the price, it worth $0.16, so, it's definitely not attractive to make a transaction when there are other altcoins like Litecoin and similar ones that offer basically free transactions.
