Building a Better Messaging System with Bitcoin
backed.ioI see a lot of potential in a system such as this. Let's build it.
Would choosing an alternative crypto currency other than Bitcoin help with some of the recognized issues?
I'm honestly not as well versed in what the latest alternative cryptocurrencies are as I used to be. However, I don't know of any that have solved the problem of blockchain bloat due to increased microtransactions.
I still think Bitcoin would be the best choice at the moment. It has a developer community that is actively working on solutions to the problems that keep it from being better suited to large numbers of microtransactions.
