I agree, many people, including day-traders are making massive amounts of money partaking in ICOs and/or trading altcoins when they are low vs when they are high. I am not saying one can't make money off of trading some of the more dubious coins out there--you can definitely have profit in trading trashcoins. However, it is my prediction that in the very long-term, most of these altcoins will disappear. In the short-term, there is profit to be made for day-traders.
