I've started to see the hype forming myself. I have a few friends that are starting to buy bitcoin while the price is still cheap, they are confident it will be back over 20k within a short time.
Don't ever to expect Bitcoin price will turn back into $20K again as it hype last year.
We already saw green color on the market and prices seems to quietly moving up but isn't enough to say that it is on hype.
Usually people treat market as turning bull when the price rallies by 20% and the other way round a 20% loss in a short time means the bear market is coming. For the price to be considered bullish we'd have to go to 8500 dollars. Anything below will not be a clear indicator and can be a continuation of the previous bear pattern.
