Ya, but don't forget the dangers of indexing in crypto, though. The reason it's been successful in the stock market is because stocks are built on top of functioning successful businesses, where it's hard for a company to just collapse and disappear on a very short time-frame (financial crisis aside).
But that is a very real possibility with any cryptocurrency. So, go ahead and HODL guys. Just don't falsely think that indexing will work with your cryptoassets the same way it has worked for you in the stock market.
And once again: Always. Do. Your. Own. Research!
The whole cryptocurrency industry won't die. The coins that make it will make it big
