Well the us government is thinking about making their own cryptocurrency, kind of defeats the point of bitcoin.
That's the point I make is that it is an active speculative instrument, it is not digital gold. There has to be an exit point if you believe the tech is revolutionary, because BTC is flawed and should be replaced by a better platform. Will it be replaced by a bank/govt coin? Probably. When have the people ever beat the banks at their own game? Never...because the govts act on their behalf. Guess who invented SHA256, which is the backbone of Bitcoin? The N S A...yes that one. Given that the "guy" that invented Bitcoin doesn't even exist, who do you think implemented all this?
As for the comparison of Litecoin to Bitcoin as Gib said - Betamax to VHS...not exactly true. Beta was the better version but the adoption of VHS was in part due to Sony being stupid with their platform and being outmaneuvered by JVC. In no way did the consumer decide the outcome on that it was all behind the scenes.
Litecoin already has the tech fixes in place that Bitcoin needs and it doesn't run on SHA256. I did some research on segwit, lightning and 4x hash rates and all that and it would seem that BTC is going to have a hard time adopting these huge changes without issues. Not to mention the developer has a real name and he came from Google. In tech everything can change very quickly. This is software after all, how old is the oldest version of software on any device you own? A few years at most usually. I think sitting on a lot of Bitcoin is a very big risk indeed, just as I would with any single speculative vehicle.
