Only invest what you can afford to lose. I think EOS will continue to decline in value until the ICO is over. I really think they made a mistake with this year-long death by a thousand cuts. Remember we are not even 50% of the way through it. I'll probably buy if it starts showing signs of moving up or at least stabilizing over a decently long period (a month or two) as the released tech starts to build some substantial buzz. Remember it took a long time for ETH to really build momentum and value. There was a pretty long period when you could pick it up for a song and that was without a year long drip, drip, drip of 2 million EOS per day and few Chinese buyers to (legally) buy it.
