Well like they say, Bitcoin is unpredictable. Have you checked the price of Bitcoin today? You can't compare that what we had in the last two days or last week. The price of Bitcoin was already down to $6,500 before coming back up to $7000 and today it has reached $7,500. I was already seeing some people predicting that the price will fall back to $4000 but that never happened.
Nobody can ever predict what will be the future of Bitcoin, it's always something else at the end. This is one of the reasons I always hold strong when I invest for the long term, because I know that people will always make the wrong prediction and say things that will never happen.
