Sweet Buttcoins is about women and investments in cryptocurrencies (cryptos). They are both sweet to learn but very difficult to understand and master. One of the few girls who knew nothing about Bitcoins referred to them as Buttcoins, which was actually a very sweet mistake that inspired me to come up with the title of the book.My cryptos investments in 2022 were the best canvas to paint an interesting story. A real events story that combines my new endeavor in the cryptos world, interacting with women online, and my studies and experience in business administration (economics, business, negotiations, strategy, and marketing), as well as my hobbies.In this fascinating new world I chose to live from February 2022, luck plays a very important role. In cryptos, it is extremely difficult to distinguish real professionals from scammers. But as stated by Tom Cruise in the opening narration of legendary Color of Money, a 1986 movie directed by Martin Scorsese, starring Paul Newman and Tom Cruise as professional pool players: "Luck plays a part in nine-ball. But for some players...luck itself is not."I believe the story is interesting as it is inspired by real events, but it is even better if the reader listens to the songs and views movie trailers as their titles appear in it, in italics, or with their initials capitalized to recognize them. The songs, movies and series mentioned in the book as integral parts of the story are listed as appendix 1 for readers to enjoy, ideally simultaneously to reading the relevant sections of the book.The punchlines of the book are the following: a) cryptos are a goldmine but also a minefield and b) in investments and relationships, trust is the most important factor.
