You may sell your BTC during the bullish period of, which may be a sign of good business. Now you bought again at the time of low market, here you stayed with Bitcoin and increased the profit margin. From this point of view your profit is appearing small but on a large scale you are deprived of big profit. In this case colored bubbles (small investors who are satisfied with little) maintain their activity in the market. Similarly, large investors tend to have a large size of buy the dips in the long term to see the ocean waves.
that's more of trading not investing or long-term holding. Trading mostly deal with buy when the price is low (bearish ) and sell when is high (bullish) which those not match with the topic here. When comes to investing or holding for long-term, we don't bother ourselves with timing the Market instead we buy at different price interval using DCA method while we hold for long , and set aside a funds (reserved funds) we can use to buy the dip whenever there's any without it affecting our normal DCA accummulation, and also make use of the other strategies when its convenience. And we keep accummulating and hodl till we are gotten to point if having enough bitcoin in our portfolio (our accumulation goal). Then we can think of taking profit from it whenever is convenience forus , like when there's surge in market prices.
