Cause it is a great way to make some quick money even in such a bearish market if you are lucky enough to be a part of some hottest ICO projects (HyperQuant is absolutely one of them). Compared with conventional ways of investment, the entry threshold is much more lower which means that you can still invest even if you are not some kind of accredited investors in some country. If you ask what is the most important reason that people choose this kind of investment way, i would say it is its extremely high ROI, for example, those who invest in ETH, NEO and IOTA in the early stage have earned hundreds or even thousands of their initial investment amount.
