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.
