Does anyone invest in cryptos? I bought BTC last year and am thinking I need to own some ETH to hedge BTC as it appears that ETH is essentially a pure play on blockchain technology

I bought some bitcoin back in like 2012 or so when it was around 25. Held it when it shot up and sold some of it around 250 before it plummeted again. See it is now over 700 thats impressive. I think the tech is pretty important and will be useful one day but I think 99.9999% of the business applications of it thought out so far are terrible. Even worse so every bank thinks it should come up with its own digital currency like everyone is going to want to use their stupid disney dollars or something
