The world is changing fast.  Banks offer ridiculously low returns under 1% that don't even beat inflation.  Keeping your money under your pillow means it becomes worth less and less every year.  Even the stock market is considered risky and speculative if you're trying to get returns over 20%.  And now, people are multiplying their money overnight in Cryptocurrency.  Simply put, if you're not at least learning about Cryptocurrency, you will be losing out on more than you can imagine.
