I think to reach 1$ for terra luna at this time is a very difficult thing, because the price decline that occurred is very large and this project also there is a threat of removal by several large exchanges that are currently very disappointed and feel harmed by the project, then if there is a new update made by the team to again lift the price of terra luna then it takes a long time to get the highest value as it has ever happened previously.
The amount of coins that they have at this point is the reason why it would keep it being a problem. 6.5 trillion coins means that if it is 1 dollar then it would be 6.5 trillion dollars and right now bitcoin is 555 billion dollars in marketcap, hence why I believe that it would be funny to imagine that.
The best I can see right now would be 0.01, so 1 cent, in that case it would be 65 billion dollars, and that is the best it could ever reach, which is doubtful. Even 0.00001 would be a challenge at this point, which is 650 million dollars and its going under that level, just wait and see. I know that its looking higher now, but it will get there.
