One thing I've learned in my short period of bitcoin investment is that dips and downward volatility causes higher panic when you don't investment with discretion. Also, buying by DCA also eases the stress of downward volatility since an investor seizes every dip to buy and has little or no time to think about the previous one bought at higher prices. Imagine buying bitcoin at 96k and eventually buying again at 80k, an investor actually feels he has gained an equivalent $16k knowing fully well that the market volatility doesn't go downwards always hence there's hope that bitcoin will still go above 96k.

That you buy by DCA does not make you want to always buy at higher prices than the previous buys. This is one of the best advantages of DCA and Discretionary income-based investment strategy. Beginners that understand this trend won't panic nor want to sell off his  bitcoin accumulation over slight market change. Investing by lump-sum is good, but whenever market "dips too low" by their standards, regrets set in because most lump-sum investments are not done with only discretionary income and sometimes greed-motivated.
