You make some great points there. ETFs is a game changer if they ever get approved...it would mean more regulation though, which gives the power back to the regulators and big government. Lightning network should be coming soon for more coins and that will greatly help with microtransactions and sending costs. Wallets need to be more user friendly, but that will come with time. Looks like Ethos is working on a universal wallet. If all those things come to fruition, then there is a good chance BTC could go parabolic...
