You haven't subscribed to this coin $XPL again; there's no reason to short it, right? There should be another five hundred million in subscriptions, which means there are still two more phases. Before these two phases end, the project team will pump the price to maintain a high value; only in this way will people go to subscribe for the quota.
If you have already subscribed, find a suitable point to hedge and lock in profits. If you are a short-term expert, then buy on dips and run away before the subscription period ends.
