Could be possible. Market dominance of Bitcoin has gone down to less than 40% from 80-90% at the beginning of 2017. With fiat pairs on other cryptos available incoming, most of the new people enter the market without even purchasing bitcoin. Even with what we say, the lightning network or any other upgrades that will come on the blockchain of bitcoin, there would still be no other use for it but just a store of value. From the 6k bounce, I think we might not see another exponential growth but a less volatile and more stabilized one.
I agree. Due to also deflation it's becoming store of value, and due to high transaction fees, it is losing it's usage for most average people. Bitcoin is just becoming virtual gold. You won't pay gold to do normal shopping like food, clothes etc. But you can buy by gold more expensive things, like car. Same with bitcoin, try to buy with it cheeseburger. Yeah it is possible, but who wants to buy cheeseburger worth 5$ and pay 12$ or more fee?
