My co-worker and I (he was into sneakers, I was into money) used to have a nice little business arbitraging sneakers. Pretty easy to make 100%-500% returns with a little code and some ebay dedication.
yeah the whole hypebeast streetwear black market is huge, especially for shoes and supreme/big drops
the most interesting part is looking at stockx with the charts they have on items, I have shoes/silhouettes that I bought on sale/new through retail that have since sold out and seeing 2x return on investment isnt uncommon
There are whole sub-industries within this bubble, too. People selling sneakerbot code, people selling purchase alert services, people selling access to private dischord groups that alert you to upcoming sales, etc. It's huge.
