Think of it this way, if the asset would fold today (hypothetically), the ROI would be -79.4% as one would not have made back much of the money they first put in.
Once you make your initial investment back, then you have a positive % of return. Till then it's all getting money back that was yours to begin with.
EVERYONE in crypto uses "ROI" incorrectly to the point nobody cares to correct folks anymore
