Eh, "no fees" is pretty meaningless when you look at the broader flow of assets outside of this single transaction.<p>To acquire crypto in the first place, I likely pay fees or have purchased mining equipment.<p>Crypto assets are also volatile, so I'm possibly losing future gains, realizing losses, or paying interest to borrow against my wallet.<p>Also, one of your premises is wrong -- that this isn't possible with fiat. I myself pay many people instantly to their bank account using Zelle with 0% fees.
