Keep your cash safe! That’s the first rule. Imagine saving up for a house. Then you find a speculative bet. Promises of millions lure you in and you finally give in only to lose it all. And you’re right back at where you started. Such things have happened before.  I want you to avoid that. Even long-term save bets such as index investing are sometimes not the right option. For example, if you’re saving for a house, short-term goals or an emergency fund.
