This is a good time to go out cheap on Luna, yea it has lots of problems presently but buying at 0.77$ and selling at 5$ today is great return, not only that, just because this project has a big issue now doesn't mean its the end, this is not a financial advice but taking risk with just 10$ - 20$ might worth it.
I doubt Luna can return to normal. this problem is very big and makes everyone lose faith in this project. although it looks profitable because it makes a quick profit, but I doubt this method will work the second time around. because right now the price of Luna has stopped moving. maybe this is already the lower high for this coin. and after this it will probably start going down without a pump.
