Seems the bcash shills have made their way to steemit, so I dont know if I should even address you, but youre wrong. First of all, becoming a store of value and being digital gold, IS MAINSTREAM USE. What do you think institutions will use it for? Mostly as a store of value. Also this whole FUD about not using it for daily transactions is stupid.

Yes you shouldnt use it for a cup of coffee (I never stated mainstream adoption would be by people using it for that), but I can send 200 dollars to any of my friends without a middle man for a couple of bucks using segwit, which for some reason the same people complaining about expensive transactions, dont even implement.

Censorshipless transactions were never meant to be free, there is a trade off. I wouldnt suggest using bitcoin as a form of currency anyway, deflationary currency usually leads to problems. As a store of value or investment class asset-currency hybrid, it can be very useful. Use your USD for coffee, theres no reason to use bitcoin.

Also a block size raise is coming in the future, but it wants to be lumped in with other things as well and lightning will come within the next few years, which for every day use, if you want to use btc for coffee, you could easily do for a tiny amount.
