So many people have experienced the last all time high of a Bitcoin price high above $18 000 in 2017 and they invested loads of money into a dream of a better future, if the price goes back to $18 000 or much higher than that.

Now, I am not saying that there is something wrong with having those dreams of making massive profits and funding future projects, because it is still a possibility.
I think the focus should rather be for us to take baby steps to that goal and the way for us to do that is to take small profits when the opportunity presents it self. The concept of buying low and selling high is as old as the mountains, but it is just as affective if you do it more frequently. The Bitcoin price has recovered from the all time low with more than 20% and many people are waiting for it to bounce back to 60% or 80% before they start taking profits again.
If you were one of the unlucky people who bought in at the all time high, you obviously have to wait for the price to recover to your entry price to break even or to make a profit when it pass that price, but there are enough volatility now to get in at a new low price and then taking small profits based on the smaller recovery increments.
If you re-invested at say $5000 and you sold lately at $8000, you could have reduced your precentage loss for the investments that you have done at a buy in price of $18 000.
A buddy of mine has done this and he wiped out his potential loss within a few months, by simply buying in low again and selling at more frequent intervals.
Ps. Also remember to spend at least 20% of all the coins you buy, to feed the merchant network and use case for Bitcoin, or it will die as a currency.
You are thinking like an intra-day trader and those that desired to play safe in case what is speculated do not happen, do trade in this way! The market has Rewards many of us here that wish to hold for long-term and I think there is no any form of investment that has given good returned for the past three years like bitcoin and crypto market! It is good to take profits with little increase in price but that may not make you rich but if you can buy when bitcoin was down in the past and hold for the next three to five years? That is what will make you to be rich and that is a very high risky thing to do.
