One of the ways to earn money in cryptocurrency related to NFT (non-copied tokens) is to sell your own NFT tokens on sites such as OpenSea, Raible, etc. To do this, you need to create a unique digital asset, which can be a picture, video, music or any other creative product, and then upload it to the marketplace for sale. If your NFT is popular and it is bought, then you can earn income in the form of cryptocurrency.

Another way to earn money in cryptocurrency can be the creation of retrodrops. Retrodrops are new NFT tokens that are used as a reward for the purchase of certain NFT tokens. This allows sellers of NFT tokens to increase buyers' interest in their product and increase the frequency of sales. Creating retrodrops can be a great way to attract new customers and increase sales.

However, as in any other field, earning in cryptocurrency is associated with risk. It is necessary to thoroughly research the market and evaluate your capabilities before investing in the creation of NFT tokens or retrodrops.
