when people say bitcoin will fall, that's where people / whales are competing to add cargo so they can go to the moon in peace in their time,
one thing is natural if they blaspheme bitcoin when it is falling, but with our faith and the strength of our hands, one day bitcoin will return to its highest point, just need patience
If we talk about the nearest future then definitely BTC to USD rates will go up and down multiple times. But if we look forward to the distant future I'd say that we'll see different new financial systems some of which will be better then Bitcoin and replace is one day as nowadays Bitcoin gives an alternative to an old bank system. So someday in the distant future Bitcoin will fall but it is not a problem, it is a blessed promise of non stopping Scientific Revolution.
