Zero fees? In crypto, there's an inverse correlation between on-chain fees and price volatility. So either you incur high on-chain fees or accept a high exchange rate risk.
Bitcoin and Nano move very closely together, yet one charges hundreds of thousands in fees every day and the other none at all. I'm not sure where you got that idea from.
Fair point. But Nano doesn't have sufficient liquidity to be used for payments. You can barely move $50k USD worth of Nano without moving the price 0.5%.
In comparison, you can move around $100 million USD worth of Bitcoin until you move its price by 0.5%.
