I hope it does lose its popularity. Great time to buy in.
I agree that it would be a good time to buy some more BTC but try to think about people who bought at the last ATH? Investors would be scared that Bitcoin has no future and they would probably switch to another cryptocurrency. Just buy and be patient, you shouldn't be here if you expect huge profits in few months. Bitcoin is great and might help us become richer but that's not its aim.
