Actually I don't have any participations in any ICO. Currently I am preferred to participate in signature bounty campaign then when time comes if I got successful to be a trader I would guaranty that I will join ico's as long as I can.
This is basically varying from person to person. Sometimes you consider trading as best option for you as it would meet up with your goals and nature of earning money. Sometimes bounty campaigns are resonating with your objectives. And sometimes something else gets same wavelength as yours. So this verity is actually the beauty of this world. Anyways, good luck.
