That is a correct assumption. The key issue is wallets that can work with BAT and can scale APIs that allow integrations easier. We just launched Crypto Wallets that will allow Dapps to work as well - separate but relevant and one can do a lot more there. The Uphold/Brave Rewards use case is very specifically related to BAT earnings, and spending between the advertiser, browser, and creators where we need to stay onside of compliance laws.
