I'd base your theory on the rise after 15th Dec (ASX stop)...so only 75%(ish?)

Prior to Dec 15 the STTTF price would have been more attached to ASX pricing and followed the 2 week rise on ASX.

Not sure they would give a private value to private markets platform...it will be what the first buyer/seller ask for and probably nowhere near that stage yet.

More likely to be something to do with the company engaged to do the private evaluation for the purpose of tax etc. Or more likely just the punters who trade in OTC thinking previous $20-30mill public market valuation that ASX punters had it at is a joke and is alot less than what the private valuation with motive at the helm will be when its calculated and in for a quick buck on their fake shares.
