Just as time wait for no man that's how Bitcoin prices wait for no man . When comes to investing in Bitcoin is good to make plans though, but don't let that plans leads to procrastination, because many people keep using that idea of planning to procrastinate, there alot of folks that wanted to get into Bitcoin when the price range was still around $50k but they had to procrastinate due to many reasons like planning, or waiting for a certain the dips but now Bitcoin is X2 of that price range (now 100k) so these are stuff procrastinating can lead to when comes to bitcoin investment.
The price of bitcoin can't be predicted and waiting for the dip to buy bitcoin is not the best. Those who always wait for the dip to buy bitcoin normally have certain price of what they think the price of bitcoin will fall to and waiting for the price the market will be going a differently from what they want and they end up not buying. You don't wait for the dip, you only grab it when you have opportunity or come across it. You don't have to wait for the dip to invest in bitcoin because waiting is not necessary, you just have to invest now and hodl and make good profit in the future.
Some people feels when they wait to buy bitcoin in the dip is more profitable but the time wasted would have been a time to buy bitcoin which value would have been achieved in all these times.
