If it were guaranteed that the price of bitcoin would stay the same as it is today, would you still buy it? My guess is, the answer is no. But if its value lies in being a currency, price stability is essential. And if your answer is no, how is it then not just a Ponzi scheme? In other words, everyone is buying it on the hope of someone paying more for it in the future, not to use it as a currency.
Not everyone is hoarding all the coins they buy. I regularly buy coins on the dip and then I hoard about 80%. The remaining
20% are being used for daily food and drinks purchases at one of our local Pubs. We use it both as a store of value and as a
currency. I would have spend that money on food and drinks in any way, why not pay with Bitcoin. {We pay in advance and
