I will always emphasize due diligence in your personal research before indulging to invest in an ICO, wether the market is bearish or bullish.
Not all ICOs have a bad record. You can see some extending  their ICO/bounty duration for one lapse or the other. Again, a situation where one person buys into a fifth of an ICO is not really good for me. Check out at what is happening to Seele and you'll understand.

If you do your homework very well; a non performing coin today will definitely have a reason for bn in that situattion. Give it more time and you'll definiely reap from your investment. Crypto trading needs patience.
