Sacred Haven of Debauchery

My attitude towards cryptocurrency is heresy and obscurantism.

Well, in general, yes. The only non-speculative benefit they offer is transferring money from point A to point B. If the exchange rate didn't fluctuate so much, then maybe it would make sense to have some, in order to buy something online. But, in general, these cryptocurrencies are some kind of nonsense, and the exchange rate of all of them will fall in the long run, if only because there are more and more of them, and there is no end to it.

I have the same attitude towards computers.

I don't know about that.

For Bitcoin, yes, but there are others.
