I invest in altcoins because it's the way to invest into your future. It may look like a big bubble, of course. That's why I choose consciously in which project to invest. The best way to profit from ICO is to invest into ideas which are already turned into projects. It is important to choose a project which is aimed at solving real-life issues. For me ICOs are the opportunity to become an investor of a real business company and feel myself equal to guys from the Wall Street. There should be more projects which offer long-term investments.
I am investing on some altcoin because I am believe they have potential to growth. Some of my altcoin have real product and already have exist consument. Beside that, I am choosing altcoin with lower market cap but high daily volume transaction
