In this case you can only do one thing "Hold", this is the best option at the moment all the weak hands who sold their bitcoin will surely regret, another thing you can also do if you have a dollar you have to buy more bitcoin Every drop because this is a great opportunity that may not be repeated in the future. The market situation is now difficult and the global economy is in a downturn so it is better at this stage to leave work and go on vacation until the situation stabilizes. Personally, I am optimistic that Bitcoin will do it this time as it has always done and come back stronger than it was.
This situation has already happened with bitcoin, it lost its price and fell to the very bottom. I think now exactly the same situation, we need to be patient and keep our bitcoins until better times. Of course, these are very bad days in the crypto world, but you should not give in to emotions.
