I agree with bitcoin specifically. When it started it was useful to me for cheap cross border value transfer and timestamping. Now we have alternatives. I still would prefer if a more efficient payment mechanism was widespread, that hides my transaction details from the payment processor.

When it started, you could mine Bitcoin on a laptop for fun. Now you need a faceless cartel of datacenter owners running rigs 24/7 and selling options on mined BTC to keep the lights on.
