I think the opportunities for quick flips are getting very rare. I haven’t had success with any of my mints. And the time that you need to put in to finding a quality project severely cuts in to any hourly profit. I would judge a project off community, artwork/team and fees. It takes hours of monitoring discord to get a feel for the strength of the community and I find that time on Discord exhausting. The artwork is subjective obviously and I would try and stay away from projects with anonymous founders. One drop claimed to be a team of women coders supporting women - nope, random Russian men. Lastly, fees. With the high price of ETH gas this can be brutal. For small $ buyers the fees especially add up(minting fees, OpenSea fees). In short I would be very careful. The best investment is CryptoPunks right now followed by Bored Ape Yacht Clubs. The bluebloods of NFTs. I would buy in to a CryptoPunk DAO before buying a random NFT. Visa just bought a CryptoPunk today and more corporations will follow. Arizona Iced Tea just announced a Bored Ape Yacht Club marketing campaign. But I would imagine none of us are looking to spend $100k on either. So a DAO you trust(do extensive research) is the best $ making approach now.
