Even some of the more disappointing ICO's can still double your money in a short period of time (less than a month). There aren't many financial instruments that can give you those returns. Especially those with a solid community backing them.Of course, you still have to keep your investing hat on and investigate into whether that company is legit, they have the right product/market fit, are gaining traction, and have a foreseeable chance of achieving their goals.ICOs can be a highly profitable way to make money with cryptocurrency, even more so than Bitcoin. With that in mind, they're also a lot more volatile and riskier than Bitcoin.
