buying when the market is dip is the right approach for an intending and existing bitcoiner but if you can't wait till the market dips, buy the liitle you can to avoid squandering the funds meant for the said investment.
You must not wait for the market to go dip before buying bitcoin, any one waiting for the market to go dip it means the person doesn't understand how bitcoin works. If eventually the markets goes dip it is a good thing to buy and never to miss the opportunity but waiting for the market to go dip can be seen as greed, lack of understanding because you can't predict the market. It is possible when one buys the market can even than what you expected, and the increase is a gain. When you buy bitcoin their will always be an increase, I don't see any reason to wait for the dip to occur to buy bitcoin. One thing I know for sure is that the dip is something that should never be miss when it occurs and should not be a reason why one is waiting for to invest in bitcoin first because it is unpredicted.
Bitcoin market conditions are predictable but reality can be different so you should stay in regular buying as you will keep stashing into your portfolio whether the price of Bitcoin is bearish or bullish. When its price goes down, the same amount of money accumulates more bitcoins that increase over time, even continuing to accumulate during bullish periods. Accumulating bitcoins for a long time also makes you more experienced in investing so bearish and bullish divergences can become more positive for you than they do for larger investors. DCA naturally becomes easier for you as your stash gets progressively bigger and it becomes easier for you to decide to continue accumulating bitcoin for 10 years or more. Since your portfolio is a decent size you can be aggressive in buying bitcoin during dips. For example, if the price of Bitcoin is going up for 6 months then you continue to accumulate normally and if the price goes down for the next 1 month then you should continue to buy aggressively. By conducting DCA in this process after 10 years you will see a huge stash of Bitcoins in your portfolio which can give you huge profits. So you should increase holdings and go long.
