Hello Bill, Why have all the Mainland Chinese Smartphone manufacturers not developed a Blockchain Smartphone, that is a Smartphone which either has its own crypto currency wallet enabled or the ability to protect other downloaded crypto currency wallets globally from Android Play Store, as there are literally hundreds being downloaded now onto Smartphones globally (outside of China) and none of wallets are protected in tamper resistant hardware on the phone and all use Android os. This is a huge security risk for the theft of the private keys in the wallets of Android os Smartphones to be stolen, and Chinese Smartphone vendors know this but it seems because their own Government bans the use of Crypto wallets inside the country they don't feel they need to worry about hackers routing their consumers' Smartphones globally to steal crypto currencies. What is the story with all this? Thanks,
