Now that the price of BTC has hit higher to break into ATH for those that hodl 1BTC over some years to made massive profits from market, this bull run that happened early this year will encourage many people to buy BTC anytime because the next bull run will be higher than what we see in this long bull run. Even though you want to continue buying BTC, don't use all your money to buy BTC because you will not like what will happen next when you are facing some financial issues and the price of BTC is low in the market.
If you invest money that is not your discretionary income into Bitcoin you are investing the wrong way. After sorting out your monthly expenses as an individual a particular amount/ percentage from your discretionary income should be invested in Bitcoin. That is how Bitcoin investment and any other investment works. As long as you dont use money meant for emergencies, groceries, tuition fee to mention a few others you wont bother about the price going up or going down as a long term investor.
The term dont invest what you cant afford to lose means dont invest any money that is outside of your discretionary income.
you can divide your capital to buy BTC and when the price drop again you can still buy to make sure you have plenty of BTC in your wallet.
You sound like an investor who is investing without a structured planned and goal. Long term investors who is accumulating Bitcoin steadily doesnt not have to invest part and wait for the dip to invest and again. That is typical timing the market and you know that when you time the market it is much likely to be seen as trading. As a long term investor you keep accumulating Bitcoin with your strategy as planned and if you eventually meet the dip when you still have some discretionary income left you can buy the dip. Buying dip should not stop you from accumulating with your preferred strategy.
