I definitely like to get in early on currencies, so as not to miss out on the large growth they all inevitably experience in the first few months on the market. I have participated in two ICO's thus far; Monaco, and Polybius. I have lost money on both of them since their release onto the market, however; they are both finally beginning to pick up. My reasoning for purchasing them in the first place was to add a source of fixed income to my crypto portfolio.
