With all due respect, it's not really missing the boat. You can say you missed the boat with Amazon stocks when they went from 50 cents to 1 dollar, but look how much they've climbed since. Btc will still climb a lot and while you may not make AS MUCH money as you would have, you'll still likely make a good chunk of money as the dollar continues to devalue and inevitably crash. There's still a huge opportunity.
I personally wish I got into Ethereum instead of Dash when people were telling me to get in. Would have made 1500% return. Oh well, as Greg says, there's always new opportunities. :)
