Bitcoin is failed. Merchants have started rejecting it, there's half a dozen forks each with their own fix for the original bad code and there's hundreds of better options like Steem.
Cryptocurrency itself might become an actual, viable currency someday but Bitcoin won't.
Even for the illicit uses there are coins that are more focused on privacy, right?
By 2028 it seems likely that there will be a new alpha coin with superior technology, and BTC will be a relic on the dust heap of innovation.
Like myspace.com. A major innovation and the market leader for many years. That was dethroned by better and faster innovation.
Why would anyone expect BTC to last forever at the top of the heap, or even to last a decade at the top of the heap, when that is a very rare result for any new innovative technology
Exactly.
