Twitter will allow people to tip their favorite content creators with bitcoin and will launch a fund to pay some users who host audio chat rooms on its Spaces feature . The feature will let people track and showcase their NFT ownership on Twitter, the company said. In an effort to grow Spaces, Twitter will launch a creator fund to provide financial, technical and marketing support to users who host recurring audio programming on Spaces. Such support will allow more Spaces hosts to organise better conversations and potentially gain brand sponsorship deals.
