You really made a great presentation here @ckole. I agree with so many of the points raised - for example on volatility being a con to cryptocurrencies.

If for instance Pizza is sold for $50, and the value of bitcoin drops after the payment for pizza, the business is at loss.

Sure when the market deeps, businesses that adopted cryptocurrencies as a means of payment will surely record huge losses. The instability in price means that it is risky to accept cryptos as a means of payment.
