While Bitcoin is the best store of value possible, I don’t see it as a currency anymore, at least for now...we will see what happens with Lightning network. I think Litecoin and Vertcoin instead being good mediums of exchange in the long run. With a price of 10k per bitcoin potentially going to 100k or 500k, no one is encouraged in spending it in real life transactions at the moment.
I think we will end up with bitcoin as the store of value of cryptocurrencies and the other coins serving their purpose, that’s why I am bullish on all of atomic swaps coins.
