Well when everyone is making the same bets calls and puts during the same time who can you make money off of? If you make a short term call then the prices will drop and hold until the expiration day causing time decay to diminish your money, if you make short term puts then it will rise and hold until expiration day causing time decay to diminish your money, if you do a short term bullish spread it will hover and you may or may not break even and the same thing with a short term bearish spread....& long term is too risky because of the high premiums...NIO has became an overmanipulated-overbought/oversold pig!
