Quite the opposite IMO. What you mean to say I think is BTC seems to no longer be in hype, but its still quite popular. While there are still undoubtedly a vast majority of people who don't know bitcoin, I think that its even more popular today as compared to the past years plus its reputation is even better as compared during the time when ICOs were booming. Because of many ICO scams back in 2017, it has tainted the image of Bitcoin and was momentarily blocked in various parts of the internet (facebook, youtube) but now you can see that they are slowly warming up to bitcoin (recent addition of crypto tab on Google Finance). This current bull run has added to Bitcoin's popularity as well, as institutions are slowly adopting. Have you even been reading the news lately?
