The non-technical side of the community can help with their support. The wallet providers and exchanges will only make decisions to implement new technologies, if there is a huge demand for it. You can write emails to these third party services to ask for these technologies. When there are enough people doing this, they would not have a choice in the matter, they have to go with the demand or they will lose market share in a highly competitive market.

Leave the technical side for the experts and concentrate on the things that you can change.
