if you understand investment policies, if you plan to hold your bitcoin for a couple of years and you can engage only your extra money (no loans, no mortgage, no selling other properties) - this is a perfect time to buy! Bitcoin is low below $8K now.
To each there own, but I've found a plan that works for me. I'm always open to alternative ideas, but dollar cost averaging and long term hodling minimizes tax obligations and stress, as well as timing risk. I know what I don't know; I'm not convinced I have a competitive advantage with day to day trading. There are some very smart, very weighty, very experienced, very leveraged players right now - they are the movers.
Part of my personal investing thesis involves watching the technology and getting out if anything 'breaks' or is proven obsolete. That hasn't happened yet, this price action is all surface level manipulation by large players that doesn't truly concern me. My sights are on the horizon.
