There was a few years long period of stagnation after every peak.
As regards price predictions. My gut feeling is that long-term the price is only going up. But there will likely be many spectacular rises and falls on the way. But I wouldn't wipe my arse with most of the short-term predictions by all these so-called 'analysts' on the various crypto news sites. They'll say one thing today and [with equal conviction and confidence] the exact opposite tomorrow --often with fancy charts to try and make it look like they have a fucking clue what they're on about
But in all honesty, Bitcoin will recover. The question is have you done your due diligence and are financially sound enough that you can wait out the recovery? A lot of people kick themselves for selling to early and never ask themselves why did they not wait it out? The reason people sell early and not wait the long game is they were to exposed to risk and needed to liquidate to stay afloat. Ask yourself this, if you can afford for your bitcoin to go to $0 and you are still ok, HODL. If BTC entering a long bear market can rekt you, you may want to consider taking a partial loss now to hedge your bets later. For the record I am not a financial adviser and this is opinion not financial advise.
