Bitcoin, our beloved cryptocurrency now stands between a forked road and it has to take 1 route, that will define it, and once the route is chosen it cannot turn back. It's now time to decide what bitcoin is, and where it is heading, therefore 2 paths are in front of us: Settlement Layer or Payment Network.
Now obviously my opinion is (and its a strong opinion) that Bitcoin is a Settlement Layer and it's not suited to be a Payment Network.
Why does it's use actually have to be defined?
You are limiting yourself to thinking within a very small box. Bitcoin has MANY more use cases than playing the role of a payment network "or" a settlement layer. There are limitless capabilities that this network has, some of which haven't even been defined yet.
So to say that bitcoin "must" be either a payment network, or a settlement layer really does put a cap on bitcoin's potential growth
Value transmission is only one small iota of bitcoins capability, we haven't even scratched the surface of what's truly possible with this technology
