Awesome pot!

Running on a decentralised treadmill does increase the value of the minted coins in the network. Minting coins outside of a decentralised network won’t have the same market value implying that there is something intrinsically different. Coins minted in a blockchain network with multiple participants has the intrinsic value of trustless consensus.

More importantly, it would be perhaps an over-abstraction to take a single coin out of the entirety of the network, given that it is just a unit on a ledger, where the state is proven through a consensus mechanism. Bitcoin though abstracted to have the idea of coins, is more of one big ledger state, and we can explore what Shar’ia has to say about accounting principles. The money or unit of exchange is a secondary thing. But the Bitcoin ledger raises the standard from conventional ledgers, this is without a doubt.

I would argue in the context of fiat vs BTC that it is Halal. I would also argue that it is a form of security against corruption. Though I am not a scholar.

The Islamic tradition and the Quranic revelation gives room for ambiguity (unless specifically stated), to allow for decisions to be made situationally and with context. Only in modern times do we try and prescribe a “one rule fits all” approach. This is typically a result of reacting to western interrogation, and superimposing western secular top-down value systems on top of the Islamic value system, which is very much a bottom up approach.
