If that's the case, such a system would depend on people being honest. In Japan, this provenly work, maybe even in Sweden - but in less honest countries, i really doubt it.
People always said eBay would never work because people aren't honest, but it turns out most people are honest.
Not to say I do or that the tax man will ever come for me, but the laws are there.
At best, maybe it could be a loss-leading gimmicky feature to drive traffic to less easily gamed traditional ecommerce aspects.
My gut feeling is that large part of business comes from regular customers. I guess the probability to cheat goes significantly down on each subsequent trade.
Canada is 1.x% hispanic, 2.x% black, 78% white.
The US is 20% hispanic, 13% black, 60% white.
Canada is a homogeneous nation.
Latin America's population is ~650 million. Canada intentionally designed its immigration system to be exclusionary to immigration by poorer people. Which is why, during the time in which the US massively boomed with Latin American immigration (1970s forward), Canada did not.
How can there be 650 million people in Latin American, nearly 70 million hispanics in the US, and only ~450,000 hispanics in Canada? A skill & education restricted immigration system that doesn't allow in typically poorer, lower skill, lower education hispanics coming from Latin America. It's extremely anti-diversity.
So the company buys used goods, but I see no mention of them selling it profitably?
All told, less than 1 in 10 second-hand-goods sellers didn’t deliver as promised. That was good enough for Mitsumoto, who relaunched the service, called Cash, in August as a new way to gather inventory for an online flea market. Total daily purchases are capped at 10 million yen, and are limited to smartphones, luxury handbags, watches, clothing and other specific items from a list of several thousand. Customers take a photo and are given a non-negotiable offer. Prices are set automatically based on data gleaned from other second-hand marketplaces and Cash makes money by reselling the goods.
Granted, it is a bit vague about the reselling.
