bitcoin is not losing popularity. and this is the 3rd FUD topic trying to push this falacy onto the community.
but i guess the OP just wants a price crash to buy in cheap.. without realising that waiting for a $1-$500 bitcoin and not buying in now, will simply mean they will regret it when it gets to $1000 and they didnt make the 80%+ profit in just a few months.
alot of people complained in march about the low price and saying it was gonna fall.. they missed the $450 boat and when it got to $650 they whinged they missed out on the 50%
I have seen posts like this since I started following Bitcoin. It's just sad to insult someone and assume their motives are crooked just because they might know less about, or think differently about Bitcoin.
Now to answer the OP's question I think Bitcoin is growing quickly. When I first talked about Bitcoin to my friends just a year and a half ago, they gave me funny looks. Now they nod knowingly and surprise me with how much they know. I sold Bitcoin to a friend of mine just a few days ago.
We've gotten a ton of media attention, and in a few short months, we've had Dish Network, Dell and Expedia begin accepting Bitcoin, along with hundreds if not thousands of smaller merchants. I've been a bear for much of Bitcoin's history (I felt it was overpriced), but I've never been more bullish: The price is only half of its peak, and we're in a much better position now then we were: The exchange infrastructure is much stronger (losing MtGox and Bitfloor hurt, I lost all of my Bitcoins, but it needed to happen) now, and we're seeing a lot of growth in acceptance and services. That's not to mention that when I first bought Bitcoin in early 2013 many of us weren't even sure it was legal.
I have a few concerns long term, but the next couple years should be great for Bitcoin.
