It's a matter of time before more companies do what paypal did. There's a lot of money to be made in Bitcoin and only a fool wouldn't see it.
Early companies that chose bitcoin like those US stores that accepted it early did it for publicity but those that do it now do it for the profit. In bull market people are more set towards spending and it is going to bring a lot of traffic to payment processors.
What I'm most interested to see is how these places react when things fly down the toilet again. It's easy to seem like a champ arriving at the foothills of a bull run. The reckoning is when we really learn what they're made of.
Maybe the stunning levels of deadness seen in 2014/15 and to a lesser extent 2018 won't happen again but there will still be a massive downturn in engagement.
