4 strategies to profit from flipping NFTs

1. Go on OpenSea and look for NFTs listed for less than the floor price. It could be a seller trying to get money fast.
Click on a collection and click on “Buy now” to see asking prices.
Compare to floor prices.
Make sure to compare attributes (i.e. obviously, an NFT with more rare attributes will sell for more).

2. Look for wild price fluctuations. For example, Krazy Koalas NFT has fluctuated in price during a recent 48 hour period from 0.06 Eth to 0.15 Eth.
Watch a collection over the period of a few days, and see if you can find patterns like time of the day, when it is more advantageous to buy or sell. 
Click on the Discord community to see what is selling, how often it’s selling, and how much it is selling for. 

3. Look for rare traits in a collection, and buy the cheapest ones, thus raising the floor price for those traits. Then relist at the new floor price.
Example, if the NFT collection is called BigDogs, and the rare trait is a crown, and there are 
8 BigDogs with crowns for sale, 2 cheapest ones being 0.18 Eth and 0.2 Eth, and all the others are 0.3 Eth and above, buy the 2 cheapest ones and then list them for 0.3 Eth or just a bit below. 

4. Look at the mint price on a website of a new-ish project, and compare to the floor price on OpenSea. 
Sometimes the mint price is a lot lower than the floor price. In these cases, it may be possible to mint an NFT on the website, and immediately sell it for a profit.
