The lightning network is not even a finished product yet, who knows how or if it will work.!
To me it seems like BTC has been hijacked by the banks, as they basically own the lightening network and is pushing for the development of it (from my understanding). They refuse to increase the block size, because it will limit their business opportunities for profiting of Bitcoin transactions...
BTC is practical for trading altcoins, and that is that IMHO. It is definitely not digital cash as it once was, and I dont imagine anyone buying coffee with BTC in the future. It is no longer digital cash, so whats the point of it really???
I guess It can (in theory) become "digital gold" with a store value. Which would make it practical for trading altcoins, but not for purchases and transactions between private individuals. So, if it just becomes something people hold and never use, will it have value? - My guess is no.
