You need
1. A marketplace account (OpenSea, Venly, Rarible.)
2. A wallet (I use metamask)
3. A crypto exchange account or else a standalone desktop wallet like Infinity. I use coinspot and Independent Reserve. You can use Coinjar, Binance, or Coinbase too. You need a passport or a drivers license to verify your identity. This is to receive your money. Once you have the OpenSea Marketplace account, make a collection on the Polygon network.
Add items and set the blockchain to polygon. (If you use Ethereum directly you will have to pay gas fees, but you can auction.)
Click on 'sell' after adding the item and set your price in Ethereum (it is still polygon). 1 ETH is roughly USD$4400 (USD$4533 as of 02/12/2021). It is important to market it in your Instagram and other social media.
** You have to add the ETH/MATIC (Polygon) wallet address for your exchange account to OpenSea so your profits get paid there. You can transfer from Coinspot or Independent Reserve to your bank account. Coinspot has smaller fees, but a larger spread (1%; 5-7%.), whereas IR has fees for instant withdrawals (using NPP in Australia).
