As long as I have more fiat to invest in Bitcoin, I usually buy when I see a price dip. About a week ago, Bitcoin climbed to $47k, but if you look at the current price, you will see that there is a dip in the price.
The price surge of Bitcoin last week really gave me hope that the bull market is actually going to give rise to a new all-time high, so all I do is keep DCAing until the price is fully bullish and has crossed the $60k price.
I am holding my investment until I see the price at which I have desired to sell it. My first selling price will be around $80k, $100k, and $120k. If the bull market comes, I will not sell all my bitcoin at once; I will sell in fractions to avoid selling everything when the bull market has not touched its peak.
