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.
I wouldnt really completely associate it with your brand. I really do not see any benefits to that.
What you could do is for example enable payments via cryptos. Set up a lightning channel for bitcoin.
If you want to help with doption, you coudl set up a system where people who buy from you, get a small kickback in form of your token if they install a wallet or something.
