Lets say that seller is completely legit and doesn't plan to scam anyone (this is not an accusation, just setting up the variables)
7 BTC for a $20k OVERPRICED watch is just ridonculous!
Hublot by definition is a "fashion" luxury watch. So even that $20k is around 15k over what's it actually worth.
Try to buy it at chrono for 20k , I just said the price for which I would sell my watch ... I don't intend to offend or cheat anyone ...is take it or leave it deal . I don't try to speculate on the price ...Simply this is the amount to let it go . Just remember there are 210 pieces sold out at launch...anyone with some experience on watches and bitcoin trend right now would easily understand that the value could go only up
About your scam accusation...first come and meet me ...see the watch
P.S. - the price at launch was about 4 BTC ( $25k in BTC at the time of buying)...please make more research ...
