Yeah, buying out-of-the-money options is a dumb way of insider trading in general, but on TSLA specifically you might could get away with it. Just don’t make your first trade right before you post to Elon’s account.
Not that it changes your point, but hacking Musk's account to tweet wrong info about TSLA would be fraud, not insider trading, since they're not actually an insider. Either way, OTM options is a dumb way to profit on fraud or insider trading.
