I don't think there's anyone that would gain knowledge of what the DCA is all about and how beneficial it is without getting stucked, except the person is very dillusional or has a traders mentality, well you've said well and if you continue following that path dear, you'll build a very healthy portfolio in years to come it's tested and trusted also nothing to debate about, glad you've experienced it.

 Anyways concerning what the OP said, the best way to prepare for the next bull run is to start now in buying then hodl and also secure our portfolio, for those who are already in the process, more patience is required and for those yet to start preparing, Bitcoin investment is not a big deal when you've gained a little idea of what it's all about so the best approach is to buy and hodl then maintain consistency in both.
