The entire premise of Bitcoin was the idea of competing currency. Before, BTC was the competing currency. Now, people sincerely interested in that concept are diversifying to the hundreds of other cryptos and Blockchain platforms. Here you are on Steemit now!
So clearly there’s some value being spread around. It’s not that interest is fading, but it may be spreading out. I‘d add that people who sold out their BTC contributing to the “crash” were mostly people hardly interested to begin with, just speculating.
