I do use StepN and should be noted that the $120 million was from the first quarter and the project has less than a year online. But that quarter GST and the sneakers were at ATH before the crash and people "invested" more than $1K for a pair of sneakers, earning were $30 dollars a day with a single common shoe and you could reach your ROI in 30 days. The numbers are different now as GST has crashed 98% and people who invested a lot in the first quarter have their ROI in years.
The FitnessFi space has so much potential but StepN has new competition in the space which they are already starting with better ponzinomics and in web3 projects are community driven and StepN community will ape to the next one.
