Luna price drop drastically and i think it needs a lot of time to revover. If the project developer works hard and make a new twist or strategy then maybe it will rise back in the near future, i already buy luna for just 10$ and wait till the price rise, 10$ is not a big loss if ever Luna didn't recover in the future so my suggestion buy and hold.
You should understand that the value of Luna can never go back to $100. Even the price of $1 looks unrealistic, since at this price, the capitalization of Luna will be more than $6 trillion. While the capitalization of the entire crypto market is now $1.2 trillion, and the capitalization of bitcoin is $570 billion.
