Obviously I would need to buy the author's book and subscribe to his newsletter.
Sarcasm aside we had such an opportunity just a year ago: crypto and NFT. High risk that potentially would've matched his 3000->150000 (50x) return. It was in the open, in all tech news channels, available to anyone with a bit of money. Ok, most lost money it seems but it's the kind of opportunity the author talks about.
In https://web.archive.org/web/20210426154653/https://www.finan... he talks about NFTs, too, with instructions how to buy them. There is a section on caution and skepticism, too. "Now you know a bunch of stuff about non-fungible tokens. We covered what an NFT is and isn’t, how they started, why they’re booming, skeptics’ concerns, how to buy one, and how to create and sell an NFT of your own."
That was 2021. Later the author changed the article https://www.financialsamurai.com/what-are-nfts/ and adds more skepticism and "Invest In Real Assets Instead" which conveniently links to his platform "Personally, I’d much rather buy real assets like real estate than NFTs"
