Brother, this question is interesting! Theoretically, it is entirely possible to create a cryptocurrency with unlimited mining, but in practice, there are many pitfalls that could bury you. Let me break it down for you; I guarantee clarity and excitement. First, can it be invented? Of course! The core of cryptocurrency is code and consensus. If you want to design a coin without limits, you can simply tweak the algorithm. The hard cap of 21 million coins for Bitcoin was set by Satoshi Nakamoto; you could certainly create a 'no-cap coin', for instance, with mining rewards that never halve or simply implement a dynamic adjustment mechanism where miners can mine as much as they want. Technically, both PoW (Proof of Work) and PoS (Proof of Stake) can support this, and algorithms can be adjusted however you like, for example, rewarding a fixed 1 coin for every block mined, never diminishing. As soon as the mining machine starts, coins come pouring in. But here's the problem: unlimited mining sounds great, but the actual outcome could be disastrous.
