I am in no way looking to be safe. I am willing to be risky. I don't mind having a book with a personal opinion of the writer, provided he is a reputable writer. It is just an approximation of the thing. If I sell at 50x gains, then the price goes up by 200% then crashes 90%, I would be more than happy. If you have one of these books giving personal opinions, please tell me.
I am not invested in crypto on a daily basis or even a monthly basis. I just bought once last year and that's it. I just need some insights on when to sell, before the big crash.
I would say that there is no book preventing a crash, but there are books that tell you how to pick and why pick something which could help you. Peter Lynch probably wrote the best books in his time, he was one of the best investors of his time and dude basically gave everyone a way how they could make money, it is all about finances and also future of a product, he even invested into something because his daughter and friends were in love with the product, he researched and figured out that a whole segment of women age between teenager years were in love with the product for a decade or more and he realized new teenagers like it as well and that is why it is never ending profit for it, he figured that out just from his daughters and friends reactions.
Basically, he talked about all the ways you can approach how to buy, and when you figure out how to buy, selling becomes easier.
