So the big hit is buy and buy most necessarily buying as at when there's a price drop and hodl then after sell when the coin is profitable, that's what is required of every trader or investors. But looking at the period we're in it could be either of them buy time or sell time we just need to know when the market is favourable inorder to profitable in the end.
Dip buying is not a bad thing, what is bad is waiting for a dip before buying, and by waiting you may miss a whole lot of buying opportunities that may present itself which is actually not cool, and it will be even more unwise to be waiting for a dip if you are a low coiner or you are seriously lacking behind in your accumulation journey, so waiting is a no no to me.
Then the rest of your statement shows that you are just a trader with the mindset buying and selling for minimal gains which will never take you anywhere or have any significant impact on your finances forever, so my advice to you is that you should buy and hold for a very long time, because that is the only way to make something huge from your Bitcoin investment.
