According to people reviewing it, NEM's Symbol has an economic system that allows you to passively earn coin rewards just as if you were mining. Which they're saying is better than staking rewards given by exchanges since you don’t need to put your coins on an exchange and you are earning actual block rewards.

You’ll earn on-chain block rewards even when your computer is turned off, and the rewards are sent to you instantly, the moment they are earned.

I've heard a lot of projects that are on Java, PHP, and C++ but what's really the most advanced these days? A privacy-centric blockchain for businesses is currently using Haskell and Rust — which allows them to be productive while writing high-quality code. Rust is great for low-level performance-critical code, while Haskell is great for high-level correctness-critical code.

Are there any specific pros and cons for blockchain developers to decide which language are they going for, or is anything fine?

Interesting to see that most people in the financing world are now entering the blockchain space to bridge the gap between traditional assets.
