Even if bitcoin or other cryptocurrencies shift their focus towards transactions, don't you think the deflationary nature of these currencies is a problem? I remember reading someone bought pizza with 10000 bitcoins in 2010. I feel that I will always be buying figurative pizzas (compared to what I could buy in the future) with any of these crypto currencies, if I were to transact with them. What are your thoughts on the deflationary nature of bitcoin etc?
