Sorry, I could not find how to delete this post.
Not all of us! I largely hold my mining earnings as cryptocurrencies, and only sell some of them for fiat when I need fiat… for example, to pay my rent, or to pay a credit card bill for things I’d recently bought in fiat.
I earn in crypto, hold in crypto, and only change to fiat for payment transactions. More and more people are are doing a portion of their financial activity this way.
I’ll leave it for others to discuss other points in your piece.
