I was told to only put $100-200 into an idea (coin), and ride it out. That way I can sleep at night, and not worry. So far all but 1 idea has paid off, and that one I am down $5.00.
Best one? Antshares (now Neo), was going to get personalized plates for sling reading that. Bought couple hundred bucks worth at 10 cents/coin.
Bought the sling when it hit $27 a coin, now that its at $46.75, well Quicken tells me its a 36,200% gain.
Got lucky, very lucky, but didn't consider it gambling, as an investment advisor had done the research and found it was one of a handful of coins approved in China. And China's population and distrust of their own government made people want alternatives. Not an unusual thought process in many parts of the world. Technology helps foster new ideas, different ways to accomplish same thing. Now when I retire, I can take my whole portfolio with me anywhere with internet connection, and convert to local currency as needed. Still need banks for the last part, when people won't take 'data' in payment.
Just don't lose your smartphone or passwords.
