You have to decide for yourself.
If you see bitcoin as get to rich scheme or way to get rich overnight, than better to give up and sell your bitcoin.
If you see bitcoin as long term investment and don't mind to wait a few years for concrete profit, than just buy more.
If you check bitcoin history, you will see that the same scenario happened before, a few times but bitcoin price always recovered.

Even though this might not be one of the best books that I have ever read, it shows the success that might be possible, even in countries where you might never have thought that it was possible.

I spend most of my flight home reading the book and it made me think that more people should write books and articles on their successes with Bitcoin to increase adoption.

People like the rags to riches stories and it motivates them to achieve the same level of success. 

Technical Analysis : Biggest failure of all time in the crypto sphere. It never works. No theory can really define the progress of the crypto market.

Reasons: Crypto currencies keep changing their ultimate fate with the surrounding sphere. There could be different news, updates and decisions that may change the course of bitcoin up rising and down movements.

The good news is: who cares? Bitcoin isn't American and the SEC doesn't rule the world. Santa Claus has more authority worldwide than the SEC.
On a serious note, yes we shouldn't care about the SEC every time. If it was North Korea noone would have paid attention to it
