This kind of gloating is lame, because it's the same sort of empty words that the Bitcoin bulls of last year were spouting off. If you really wanted to bet $10K that the price of Bitcoin would be less in a year, you would've shorted $10K worth of Bitcoin on one of the many exchanges that allowed it last December, and you'd be up about $50K today. Similarly, if you want to bet $10K today that it'll be higher in 2019, just go buy $10K worth of Bitcoin. If you're ultra confident do it on margin, and then "not having $10K to bet" is no impediment.
