Bitcoin recurring buys

Man, I am so stupid. I wish I would have done what Coinbase told me if I would only put in 200 a month every month since 2020 that would’ve been about $12,000. It would’ve been $50,000 now! I want to ask you guys are you guys doing that? That’s the best way to do a dollar cost averaging then trying to time the market should we wait for bitcoin to go down? I believe bitcoin can get to 300,000 one day what do you guys think?
