Market corrections can sometimes also provide entry points that investors can take right a way. If an investor has cash and is waiting to invest in the crypto market, a market correction can provide an opportunity to invest at a lower price.
We must always look at the opportunities that are created within the market, even a person that is heavily invested in bitcoin and witness a correction can take advantage of it, but how? That is the moment to dollar cost average and buy bitcoin for a cheap price, this reduces the overall price at which you bought bitcoin and it lowers the breakeven point, this is what those that invested in 2017 at the ATH should have done instead of panic selling their coins as they did.
We should understand how they reacted since it's the first bull run and they are still in doubt if bitcoin will rise or will just dump because some experts are saying that bitcoin is just a bubble. At least seeing the market now will make them realize they make a huge mistake and that they should make the right decision this time.
