There is no success that can be achieved within 1 day, of course HTC realizes this and is ready to take risks by adopting Blockchain into their phones, of course it will have an impact on their market, whether to boost sales or not.
If you can boost sales, there will be many other phone companies that will follow this step, but if the results are not as expected, they will continue to make improvements for the progress of the Blockchain implementation itself in the world of phones.
I'm sure this will reap success soon or later.
