I think DCA is much better to use especially in this period or if you were just new in the market. Besides the marketcap that bitcoin does have, it will certainly increase its value over time, so using DCA as your strategy is not a bad idea compared to relying on your gut which is kinda vague and has no certainty. To be honest, if I only knew that Bitcoin would have this much growth then I might not have spent some of my Bitcoins before.
