I think that BTC was in a bubble in 2017, but that is almost nothing compared to new bubbles which will come in next few years. BTC is nothing like tulip mania, because tulip bubble burst only once and never came back.
Tulip mania doesn't have anything to get relative to the bitcoin. What we see with bitcoin is the real growth, at times there were little price manipulation and the same gets termed as bubbles if it provides with a large scale profiting. Growth waves will continue to be a part of cryptocurrency, and this at times gets mentioned as bubbles. Nothing is gonna happen on these indications.
Bubble when burst never return back but this is not what happens with bitcoins. Bitcoin might make lower lows in bear trend, but it do always recover well. Since bitcoin adaption is increasing on daily basis, we will less frequently see the bitcoin pump and dump situation and bitcoin will rather emerge as a stable currency.
Yep, that's right, so indeed bitcoin is a bubble, but wait, how can we categorically says its a bubble when it can recover after being burst? And that is the mystery that's why many are intrigue about it and why many are anti-crypto (specially those old fart/traditional economist).
