Questions;
1. What if the deep never return?
If it is Bitcoin's dip you are referring to, then be rest assured that it will surely return, because this is not the first time Bitcoin is experiencing a dip and yet recovered fully after several weeks or months back into it's normal price and yet still creating new All Time Highs.
2. What really determines it return?
It's strong community and the people who believes in Bitcoin as a worthy alternative to fiat is actually what determines its returns after a big dip in its price value. Because as long as people still believes in Bitcoin and keep buying it as their preferred asset for the future, it will always remain valuable and recover after each market dip.
3. Do you still place more value on crypto despite its short falling?
No, I don't place more value on crypto generally after they fall during a dip, but it you mean Bitcoin, then Bitcoin is the only crypto that I strongly believe to recover after each dip, since it has a community of millions of people who believes in it.
4. What is the advantage of the deep outside buying?
Buying a coin during a dip is not an advantage, but been able to see your profit double or triple after buying at the dip is what usually matters. Because it's not everybody who buys Bitcoin at the dip are patient enough to hold till when it's value skyrocket again.
