Over the time I saw so many people cash out and move on with their lives or just lose interest, I saw many who lost a good amount of money and I saw few who made huge profits.... this forum is losing its traffic and even existing members are contributing less than before or already quit the forum, everything point to this cycle happening again, which imply to Bitcoin's price last year being a real bubble, at least this is how a bubble exactly looks like.
even the Google trend is bearish, the search for Bitcoin is going down to pre-2013 bubble I don't think Bitcoin is finished but I think we stepped to the mainstream that everyone was asking for, and a 100x a year wont really happen again, so assuming that Bitcoin will not be taken by something better or by a technical issue and assuming that using it will become easier and more secure, there will be a healthy and constant growth in the future (once we reach the bottom which is still far).
right now, everything points that Bitcoin's fundamentals are still working, and the transaction chart points that existing holders started using their bitcoins more than before, one explanation is that there is more and more places to spend your bitcoins at, and the the bearish market makes people want to spend their coins more than hoard them hoping they will be worth more in the short term.
