Having lived through the 2014-2015 downward spiral, I feel like crypto is just in a period of flushing out the dumb money. I think an uptick by the end of this year is likely and a real boom a year later is possible.
Last time there was a crypto winter, people were saying it was never going to recover. Looking at the hashrate, I could see the bitcoin network was still growing, so someone was investing in machines. You can see the same uptick in hashrate now: https://www.blockchain.com/charts/hash-rate
I actually really went deep into this and used this situation for my Master dissertation. After getting my master, I edited it and got it published in a academic journal. I calculated how much money was invested between 2012 and 2016 and found that mining is a super risky market. In that sense, a downturn every once in a while is needed.
