Crypto into payments can be seen all around as Marketplaces have begun to accept bitcoin compared to the past. There is also some form of issue relative to it which is the transaction confirmation. At times there will be more transactions stuck on the network due to congestion. This is not fair when used into businesses, so more advancements is a must for using bitcoin as Payments.
Until BTC is volatile, it cannt be used as a payment method. It's fraught with loses and inconveniences for users.
Bitcoin is very volatile and can be more profitable so better hold it than used on the market. Though there is store that accepts, I cannot see how many going to give up there coins for that or just choose to used fiat instead. There is no fruit as 2019 goes by on half year.
