We can't compare the E-payments such as the Paypal to cryptocurrency they have to understand first what is Bitcoin and other Cryptos they might be surprised of the price change of the Bitcoin and cryptocurrency compared to Paypal and other E-payments. Cryptocurrency is volatile.
That's right, we can't really compare the cryptocurrency in other E-payments because crypto is volatile and the ones we are using for e payments are not volatile and that is one of the main reason why fiat is more good to use as a payment method because of it's stable value unlike the crypto that may dump anytime. This is also a barrier why most of the people doesn't like to use crypto as payment but they are just using it as an investments into different assets.
