The internet it is great but whats to stop some new internet from being developed ...
I think that's not really comparable. But perhaps it demonstrates your point. A new web may be created out of dysfunction of the current system... a slow process of adoption. Maybe the growth of Tor etc.
I was wondering weather it is worthy "investing" in other cyrptos.
I think the answer is: maybe, but it will only become worth anything if it becomes adopted, and it takes a lot for that to happen with BTC presence.
