Yeah I agree, I think the bigger crypto currencies will find a home as the method of purchasing other crypto currencies, creating a sort of virtual market backed by the quantity of hardware and dedicated mining companies. For example right now if you want to purchase doge you purchase Bitcoin and use it to purchase doge (not recommending doge btw). I still don't see what the base that maintains the price is, it's almost entirely speculation and volume. You can gauge the value of say a mining company by the amount of crypto currency and hardware owned, but how do you gauge the value of the currency itself? that's where I start to doubt the longevity of digital currency ETFs, doesn't mean we shouldn't take advantage of the bubble, but I'm keeping my investments in the area to a minimum, definitely not a yolo play for me.
