Should I keep holding it? $NIO Inc (NIO.US)$

$NIO Inc (NIO.US)$ if you didnt manage to sell at $50 above, dont bother to sell now. manipulator might be buying back if you sell now, so when u sell they buy back.
So when it go up 55 again they sell, by the time u notice and panicked sell at below 50, they buy back again. the cycles goes on. its either you:
(1) play mid term, wait for $60 at least
(2) short term, $52-$55
(3) play long term, wait for moon $400 like Tesla
