Best Cryptos/Blockchains in your opinion?

I love the crypto and blockchain world mainly because I see it as a very innovative and powerful technology. Because of this, almost every time I bump into a new project I quickly fall in love with it (for example yesterday I discovered the Terra ecosystem and my reaction was like 🤯)

So, if you are like me I have an hard question for you here: What are the top 3 blockchain-related projects you find most promising? And why? (please consider only the technology behind them and not possible profits they can generate as investments)
