I always record every bitcoin purchase on Coinmarketcap so that I know the average price purchased and the ROI I get now, so this is not too much of a headache for me.

You are doing good practice but if any newbie is still curious and wondering that DCA is good or bad for their investment, they can create an account on Coinmarketcap and do regular DCA with their demo account. They will see DCA effects that are good for investment in long term but they will miss some time and chances to do it with demo DCA.
Bitcoin is like bluechip stocks. The longer it stays in your account, the better return it gives. You can use any simple portfolio apps simi6to the CMC one. Keep it simple!;
Perhaps you did not mean it, your account, I hope it means your non custodial wallet, not exchange account.
The HODL camp map may be a non-illustrative map or we are not used to seeing it, so it is difficult to read, but its philosophy is simple, which is that profit is achieved within more than 4 years. Losses occur if you decide to buy after 6 months of halving with the intention of selling in the short term, so it is a representation in a way Or another for the 4-year bitcoin cycles.
Bitcoin market cycle is about 4 years but the map shows us an interesting fact, if hodlers can hold their bitcoins more than 5 years, they surely get profit so far.
Because each hodler can have different entry and exit time and consequent prices so they can enter at very high price, stuck there and if they only hold their bitcoin like 4 years, they might have loss, even it is very small chance to fall into that minor cases.
If they can think bigger than only one market cycle, longer than only 4 years, they will have a safer investment strategy and also get better opportunities to gain profit.
