Of course there is the opposite side of the options: selling them. If you think their price is too high, sell them instead of buying them. For calls, unless you own an equal number of shares this can be really risky. Thus when you think about selling them, suddenly you might think they are too cheap. Especially if you are using them in a leveraged way.
One lower-risk options strategy is to buy 100 shares of stock and simultaneously sell a call; if you sell the call above the current price, then you have effectively bought the stock for a slightly lower price (the price minus the premium you collected for selling the call), but you have also limited your potential gains to the amount that the strike is above your purchase price. You also got a little bit of down-side protection because you got the shares at a bit lower price. I sometimes employ this strategy with weeklies, when there is only 1 week or less before expiration. An an example from today's closing prices:
You buy 100 shares for $310.10/share (cost $31,010.00 + commission). You sell a (one contract) 310-strike July 20 call (4 days to expiration) for $6.80, (proceeds are $680 - commission). Now if Tesla goes up (or stays the same) then the call will get assigned and you will be forced to sell the stock for $31,000.00 - commission. But you will end up keeping $670 minus 3 commissions, regardless of how much the stock goes up. If the stock goes down then you will keep the stock which effectively only cost you $303.30 plus 2 commissions, so if it only goes down a few dollars, you are still ahead. If it tanks you will lose a lot, but still less than if you just bought the stock. Now imagine that it goes up and down but ends Friday at $307.75, you keep the stock, you're ~$4/share ahead of a pure purchase and you can sell next week's 310 call for another 5 bucks or so on Monday (assuming not much opening gap).
So first paper-trade, then trade options in a non-leveraged fashion (like above) until you understand them. Then you can speculate. But always be aware of how much total $ value of stock you are trying to control; 20 contracts is 2000 shares of stock, or $620,000 worth at a 310 strike - if your account value isn't at least comparable to the dollar value of stock you want to control, don't even think about it.
