So Bitcoin is going up and up and up and I don’t know whether I should buy now or wait for a dip. Because maybe there won’t be a dip? Or maybe there’s *always* a dip? I meant to do dollar cost averaging and just buy a little each month but start now or wait? (I already own a tiny amount.)

Normally there’s no “wait” for a good entry point in a DCA strategy, you just start asap. You need a long timeframe for the positive effects to mitigate exactly the questions you raised. 
No financial advice, I’m not an analyst or anything.

You’re right. I should just pull the trigger. Start today and hope I earn a little extra spending money for my retirement.

What Rick said is important though. If you do many small invests, fees add up and eat into your margins. So be sure to do some comparison for good offers.
