I think the popularity of bitcoin is on the rise and it's not that we're losing popularity because there are more and more people who know it now and more and more people know about the encryption market and the blockchain.
What about those who came to realize about Bitcoin's scaling issues and those that have stopped investing in it because of the fear that Bitcoin might be regulated soon?
Some of people who stop investing here because they loss a little or all trust to crypto specially bitcoin.
I can claim that i dont lost my trust to bitcoin but the other might be loss it.
Not only about regulation, but most about the huge correction made from FUD news.
