Upvoting more for your advice that the idea that the Winklevii ETF will be a big deal. As I recall, it's going to be listed on an exchange that nobody has ever heard of.
I think Bitcoin will sit on the launchpad until Core releases Segwit and we see that that goes smoothly, followed by the start of a flood of innovation and continuous scaling. If none of that starts to happen by fall/winter, I'll start something of my own--swapping out of BTC for whatever.
