Buying every dip is easy to say, but difficult to identify the dip (for me at least!)
Every time the price of bitcoin drops I am afraid of the point that it is going to stop or it will be ongoing for a long time. Looking at charts and trying to make my TA sometimes prove me wrong!
Exactly I use to be this confused in trying to know when to buy the dip and as well identify which one is suitable to buy, cause it would be ringing buy buy buy buy one needs to be very careful and watchful on it rather than ending up buying some shit coins that won't be profitable in the long run. And for the price of Bitcoin it'll definitely follow this simultaneous manner of upward and downward movement and constant change in price and surely there would be an increase that would be favourable to investors and traders too what's required is patience.
You actually quoting an old post, well accumulating Bitcoin regularly using the DCA strategy will be the best to accumulate Bitcoin so you can be accumulating Bitcoin even when the price is dropping than trying to compare when it's best to accumulate Bitcoin.
If you have a reserve fund and there is a decline in price you can accumulate aggressively making good use of the market dip and accumulate enough Bitcoin and still be doing your normal DCA regular consistently every weeks or months.
