Twitch has rather silently removed crypto payment options for subscribers, eliminating Bitcoin Core (BTC) and Bitcoin Cash (BCHABC) as options for people to pay for subscriptions.
A Reddit user noticed the change and made a post saying that both BTC and BCHABC were no longer an option when it comes to paying for Twitch subscriptions.
While no reason was given as to why Twitch moved in this direction, it appears that the decision was based off a lack of demand for the option.
As of this writing, the bitcoin payment option is no longer available.
