What is actually unconscionable is that when the nature and consequences of inflationary money are exposed, the discussion immediately gets shut down. If the people were to understand what real money is, and it is not the national currency, then people would hold it instead of holding the national currency. Hint: real money is things like GLD/VTC/BTC/PAXG/XMR. Secondly, people also are instructed by the consumerist system to spend as much as they earn, effectively to not save or invest. Controlling the narrative about money is how the rich control the poor.
Can you use it for the main uses of money, store value and payment? No, you cannot, because it's very volatile, and very slow and expensive to transact it.
It's as much "real money" as worn t-shirts from sports players are.
The volatility comes with its reward, which is price dips for buying cheaply and price appreciation. Bitcoin Lightning Network is its solution which is cheaper to transact in for those that accept it. Personally I would use Monero for transactions.
