Great article that should be read by anybody who wants to buy some bitcoin or other crypto currencies. The main take away is to use the DCA method to take advantage of the volatility in the market.
We as an experienced bitcoiner, already knows all the stuff listed by the OP but still thanks for that. We can always re read it again as a form of review. The one that needs it the most are those who are noobs who are only getting started their journey in cryptos. Indeed that everyone should use DCA as it was the best strategy so far, this is because the market is so unpredictable. We won't know what if the price dips more? So, it is always better to have a spare cash in hand than doing all in most of the time.
I have been buying bitcoins since the start of the year myself, and its so much better to spread out your purchases across multiple months instead of buying everything at once.
It must be a good approach hence congrats to that because your timing was so perfect. You can start selling now if you want to and still earn something.
