Insider trading of illiquid altcoins would be silly for polo considering they likely bank over $125mm/year in fees.

Also, can't put much say into low res images of arbitrary trade dates... The coins listed all dumped because they just came out of a 3-8x pump from whoever was systematically organizing these. The delistings are likely a response to potential regulatory scrutiny that would come from being the platform that hosted all the pumps. I stopped putting any stock into coinidol after their ridiculous "trial" they kept advertising.
