Do you truly believe in crypto?

I was really hyped when I learned about bitcoin, was equally hyped when I learned about steem. However, it seems to gotten a bit silly lately, especially with NFT and now Defi offering to use NFTs a collateral for loans: this sounds to me as a recipe for bubbles, and will have repercussions beyond the crypto sphere, I fear. I am getting back to investing in more tangible stuff, like precious metals and tools and land.
