Yes, but technically we can't. Cryptos don't scale yet. And the only way to get in to them is by exchanging fiat (mining is no longer realistic for individuals and both bitcoin and ethereum are highly centralized in mining as well as distribution).

This is why I am combining a centralized approach to the decentralized nature of cryptos. It can be distributed this way. Everyone gets 50 ECOS in oecosystema (initial supply is 0). OecoSystema: https://bitcointalk.org/index.php?topic=5079577.0
