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.
yes the point is DCA is a good way to accumulate btc and certainly by using the DCA method I personally also get good benefits. but in my opinion buying btc does not have to be DCA because using any system in my opinion is a good way for example Average down or others are also good as long as we have the goal of storing our btc for the long term because of course in my opinion someone does not succeed in investing in btc because they do not store it for the long term. because if we store btc for the long term buying when it is low or high of course we will be lucky in the future because btc will never disappoint its holders as long as we are strong enough to hold btc and do not panic selling when we get a loss and of course only sell when we get a profit.
but the dca method is indeed the easiest to do because we can buy without thinking about the price of btc and indeed with the fluctuations in the price of btc sometimes we are lucky to buy btc at a cheap price.
