Forget about rumors about Facebook holding bitcoin. That news was put in use by the media for them to have a coverage that has been awaited by its audience.
I've read an analysis that the bull run that we're seeing is just the start and really the comparison to 2016. Which means, the 2017 bull run hasn't arrived yet which might be until 2022 with most of those speculations.
I don't think it's wise to compare the market back in 2016 with today's situation. The Bitcoin market cap has increased substantially since then, therefore, the price is less volatile right now. The corrections can take longer, but they will be more lasting, so I don't think we're heading to the top of the bull run same as it was 4 years ago.
If we base our predictions on patterns in the past - then we should expect the price of $300k pretty soon, and I don't think that's happening in the nearest future.
We no longer need to compare what happened in 2017, because the bullrun this year is much different now. In 2021 Bitcoin is more stable
and volatile is not that high. Perhaps with many large companies investing long-term in Bitcoin, it makes the Bitcoin price less volatile.
Moreover, this year the bullrun has run longer, and there is a possibility that it could be throughout the year. Therefore many Bitcoin holders
do not intend to sell their Bitcoin in the near future, even though now the price of Bitcoin is very high. Because they believe the price of Bitcoin
will rise even higher at the end of 2021.
