I’ve said it couple times before.
As an actual payments mechanism, bitcoin sucks.
It’s expensive to use and getting ever more so. It can be slow and unpredictable. It’s complicated and very user unfriendly. It depends on untested third parties for usability even more so than conventional electronic money. If not foremost, the more of a speculative asset it becomes the less useful it becomes as a currency.
But that was only my opinion.
