In my humble opinion, that's indeed the best way to play most crypto. Don't plan on owning the asset long term, instead own the tools around it. Or play the swings.Even 5% is tumbling IMO. But other people can think otherwise.
All those banks and exchanges (like CME etc.) do not even recognize or support cryptos. But they want to profit from the "trading" of them. This is why during the old Gold Rush, the folks who made most of the money were the tool makers, restaurant owners, merchant stores and even whorehouses. Some gold diggers got rich with the gold. But most came back empty-handed....
