But is there a statement posted anywhere that explains their decision behind this change? I couldn't find anything on that support page on Circle. I would assume their business plan with Bitcoin has gone south and they have lost customers or something and it's not profitable any more to invest in the Bitcoin infrastructure. Or is there something else? I would love to read an official statement about this.
Edit. I found it: https://blog.circle.com/2016/12/06/spark-new-markets-app-messaging-and-bitcoin-changes/
In a nutshell, Circle are building fiat-to-fiat social payment platform that is going to run on Blockchain technology.
Yeah guys, vanilla Bitcoin Blockchain is dead. The future is fusion.
