What if I launch a cosmetic brand completely associated with crypto in some way. Like , the purchase of cosmetic products of my company being available only with certain alt coin.
That's one way to start a business but it is available for purchase only using that specific altcoin can be a pain in the ass and might scare away a lot of customers imo. Even with the option of being able to buy that specific altcoin in the shop, most people have shortened attention spans right now so they'd most probably shy away from buying said products still. In addition, it's a completely new brand, so you can't expect a loyal follower base that can help the business stay afloat until the coin gets more notice from others.
Other than that issue I reckon it's pretty good. The same issues from regular businesses would naturally crop up but that's part of the process. .
