If you compare the dow jones, or the S&P 500 to the bitcoin chart you can notice that the stock's have been in a rally since 2009 right when bitcoin was just created, this means that the crypto currency space has never experienced a stock bear market, because stocks have been bullish since 2009 and right now they are starting to fall and I believe there will be a bigger crash than the one that happened in 2008-2009, based on this we can say that all the thousand's of bitcoin "deaths" where just mere corrections, like when bitcoin went from 30$ to 2$ when it went from 1200$ to 200$ and now from 20k to 3k all of the previous corrections where with a bullish stock market, but now the stock market for the first time since 2009 is beginning to plunge and is taking cryptos down with it, something that hasn't happened in the previous btc "deaths"

This makes me believe that this time crypto may never come back at all, like when tulips crashed in the 1600's or when the thousand of .com stocks never recovered (like pets.com) etc this means that this time bitcoin and other crypto currencies may NEVER come back to a ATH like it has happened before, what we learnt from previous bubbles caused by a new emerging technology eg the .com bubble with the rise of the internet is that the majority of companies (this time coins) die off and I believe right now bitcoin is so old, rusty with high tx times and high fees that it is possible it may become the MySpace of crypto, having said this it is also really posible that cryptos stop existing at all, because there are coins that really don't need a blockchain and are just pump ICO'S that have no real purpose, the only thing that its left is the blockchain technology by itself that dosnt really need to have a token with value attached to work, the world could adopt the blockchain technology without the need to have a pump token attached to it.

this is my opinion right now, I think blockchain technology is here to stay but I put into a debate if crypto tokens will be here to stay.
