Seems dumb to invest in more than one coin because there isn't really different asset classes in cryptocurrencies yet.

ETH is the only coin that could maybe convince me that there will be 10 years from now. Oil & Gold analogy etc.

I'd be willing to invest in a coin that could actually scale to VISA tps and be a stable currency and nothing else.

Perhaps we could end up in a situation with Bitcoin - Ethereum - ?? crypto fintech holy trinity (imitating gold - oil - dollar).

It remains to be seen if coins in the storage / eco / social networking / privacy asset class are the solution to the those problems people are looking for.
