I just read something very interesting in their Monetary Policy explanation!

"Currencies with set supply are extremely experimental. Miners likely need incentives to secure the chain beyond only fees. Note: currency deflation is historically not a good thing."

I had never asked the question before: What happens when if in a few years the mining rewards fall bellow a level which can support all the produced ASIC miners?
I guess many people might think that the Bitcoin's price will magically go higher in order to keep the mining profitable, just like many though the price couldn't go bellow 5000$ (or was it 4500$?) because mining would become unprofitable.
What will happen in about 1.5 years when the next halving takes place if Bitcoin's price is still around 4000$? Most likely half of the mining hardware will shut down. In that moment, there'll be enough dormant hardware to 51% attack Bitcoin itself. Scary stuff.

On that regard, GRIN is more balanced and future-proof safe.
Bitcoin's limited supply sounds good to investors, but there are some serious implications in the long term.
