I think people confuse these:
cryptocurrencies =~ digital assets and =~ blockchain too easily.
Every cryptocurrencies could become worthless (it is improbable, but possible). Digital assets on valid blockchains are less likely to. The underlying blockchain technology is further less like to.
What everyone doesn't understand is that yes "Bitcoin" could be a bubble...But cryptocurrency and the technology behind these Blockchain/Tangle/etc. along with the major partnerships aren't going anywhere. Bitcoin could pop, who knows, but other cryptos will rise to the top. That is a guarantee.
I ran a little analysis on BTC corrections going back to 2011. The rebound on average takes twice as long as the correction. So assuming today is the low (and I don't believe it is, I'm seeing 7500 at a min) then we are in for a 45 day min. recovery. Sit tight my fellow hodlers and traders
So HODL yes, but patience is required for that. Expecting unreasonable returns on unreasonable time lines will lead you to become disappointed, and then disillusioned and then cash out.
