Oddly enough, Bitcoin is probably the only Virtual Currency which cannot be used as a currency.
I think Bitcoin has became a FAD. Somewhat of a mix between a collector's item and a financial instrument for the filthy rich.
Other than being used as a trading tool, bitcoin is pretty much useless, isn't it...? A lot of people know this already... and I won't be surprised when the markets catch up with that info.
More than half of all Bitcoin UTXO's* have become unspendable. This does not happen to robust currencies, or even "stores of value". Bitcoiners were outraged when India removed the smaller denomination notes of the Rupee from circulation, but you hear nothing when the exact same thing has effectively happened in their own system.
* A UTXO is the equivalent of a coin or note in physical fiat currency. Imagine that every $5 bill you owned cost more than $5 to give to someone. That is what has happened to Bitcoin.
