this is a difficult one
while its fork SushiSwap (partly scam tainted) traded as high as $15 and traded for a few days between $4-8...
selling UNI at $3 would be wise? maybe, maybe not
BUT no one knows
what if we have a Token price war and both start to pump :D
then users can get a cut of their profits :P

Also please read the article till the end
UNI is coinbase company
