OpenSea – Selling Price

OpenSea mandates all first-time sellers to pay two fees before making the first transaction, as was already mentioned. Be aware that the cost of these two fees isn’t set, and with the right knowledge, you may minimize them as much as possible. Yet how?

First, ether is used to pay the fees. This implies that the price is based on how much the cryptocurrency is worth in terms of the dollar or your local currency.

The two fees are transactions on the Ethereum blockchain, just like minting. They require processing power to finish as a result. You must pay a gas fee to cover the cost of the energy used to conduct these transactions.

The initial transaction can cost anywhere from $70 and $300 as of this writing. The second exchange often costs between $10 and $30.

The cost of gas accounts for this pricing range. On some days, the fees are greater, and on other days, when business is slow, the fees are lower.

With, you may track the price changes. The best days to look for are those with numbers below 100. To save the most money, establish the account at this time.

In addition to the upfront costs, OpenSea retains 2.5% of your sales. This tax is only due after the item is sold.
