I know where you're coming from. If I could imagine, back when I was buying Bitcoin for $6 each, how big it would get, I'd never have sold it for $10; I'd be a millionaire today. I've been breaking out of my limiting thoughts this past month, and I'm envisioning Bitcoin and other crypto such as Dash and ETH reaching 100x their current value within just a few years (and maybe that's still being conservative!). Doesn't mean I won't sell a little on the way up though ;)
