It's never a good thing seeing Bitcoin get dropped to be replaced by whatever shitcoin. To be more precise, it's actually embarrassing. I however find it very interesting that despite of there being a huge load of pretty capable coins to choose from, they are looking at Stellar and Omise. It makes me very suspicious towards the real intentions behind this move -- it reeks of a heavy bias towards these coins, probably because of one or more figures on the top of Stripe being major holders. But hey, it's their choice at the end of the day, so regardless of we agreeing with their decision or not, it's their right to switch. They'll be back once lightning network and they are done with dumping their stashes on the market....
I have noticed that a lot of companies and not only them are recently rapidly dropping btc. As I hear The DarkSide is going for Monero.
And YES, why Stellar and OMG, this seems very odd. There are so many popular and better options, seems weird.
