Wallets used by cryptocurrency exchanges are somewhat vulnerable to hacking. For instance, Japan-based Bitcoin exchange Mt. Gox shut down and declared bankruptcy a few years back after hackers systematically relieved it of more than $450 million in Bitcoin exchanged over its servers.
When Bitcoin’s price exploded in late 2017, so did the interest of the general public in cryptocurrencies. Internet searches for Bitcoin, cryptocurrencies, and crypto prices skyrocketed. Many people weren’t able to resist the fear of missing out on the massive gains the early adopters were experiencing as crypto prices rose quickly. When the inevitable correction came and crypto prices fell, those who bought towards the end of the bull run immediately saw the value of their holdings halved. Despair and anguish followed, but the enthusiasm of the crypto community hasn’t faltered.

Sorry I wasted time on this, I don't do many reviews but just could not take another add. Threw the book away. Wasn't a bad book. Although I felt she wanted you to jump all through the book by suggesting jumping from one section to the next. Also I felt like I was reading a investing book written for feminists. Women have been in business for years, we get it. YOU CAN DO IT Better organized, better edited, better info. Current and best of 4 books I've read on Crypto. Admittedly, I've only read about 1/2 of book so far, but this is the one I would recommend over others. I would also add it is the BEST Dummy's book on the subject! This is what the the first Dummy's book should have taken the time and researched to become. The earlier Dummy's book read like an anthology created by committee rushing to get their book to market for $$$, and not for being thoroughly researched, non-redundant, and a value to the reader. The previous Dummy's book on crypto was the worst Dummy's (I've read 8) book I have read. This was among the best. Each time the author approached any subject there was a characteristic avoidance of substance. If you want to read the same tired, knowledge-vacant text then this book is for you. For everyone else, this is a waste of time. As a crypto newbie, I've been grateful to get cryptocurrency info from Kiana via her articles, her YouTube interviews and her website InvestDiva.com.
