What is selling calls for rental income? What is Ladder Selling Call? What is cumulative put? Options, dual currency small details I have read the options for selling Call to collect rent from @ BTC_options and @ CryptoRounder, and they are written very well. I am currently using a similar strategy, of course, I am using dual currency, but considering that many users may not understand it, I will explain in plain language what selling Call to collect rent is. Assuming that Bitcoin: native is currently $60000 If it is judged that we are currently in a bear market period, even if we rebound in the short term, it is difficult to break through too much. Therefore, we sell a virtual call that expires this Friday, for example: Selling a Call with an exercise price of $68000 and assuming a premium of $300, the logic at this point is: As long as BTC does not rise above $68000 by the time it expires this Friday, this call will be reset to zero, and the $300 royalty received will be the profit. If the following situations occur: 1. BTC was less than $68000 at 4:00 pm Beijing time on Friday, and the call was reset to zero, earning $300. 2. A BTC was over $68000 at 16:00 Beijing time on Friday, and Call was penetrated. If the BTC at that time was $68200, with an intrinsic value of $200, and a power deposit of $300 was received, then a profit of $100 would be made. On Friday afternoon at 4:00 pm Beijing time, if B BTC exceeded $68000 and Call was breached, and the BTC at that time was $70000 with an intrinsic value of $2000, a power deposit of $300 was collected, resulting in a profit of $1700. So the essence of selling Call for rental income is to use the risk of skyrocketing to exchange for a premium income. Talking to people means not believing that Bitcoin will skyrocket in the short term, so BTC that cannot be sold will give you royalties. Of course, the risk is that if BTC suddenly rises sharply, selling Call will result in quick losses. So many friends don't sell at one price at a time, but instead sell calls in a tiered manner. So what is tiered call sales? For example, BTC can be sold for 60000 US dollars like this: Sell 66000 calls for $500. Sell 68000 calls for $300. Sell 70000 calls for $180. Sell 72000 calls for $100. The advantage of doing this is that if the price only rebounds slightly and a few calls return to zero, all the premium can be earned smoothly. If BTC really rises, not all positions will be penetrated at the same position. So what does it mean to accumulate Put during a rebound? Still BTC 60000 USD. If BTC rebounds to $62000 or $63000, thinking it's just a bear market rebound, then buy Put. For example, buying a Put with an exercise price of $58000, assuming a premium of $800 is spent, if BTC falls to $55000 later, the maturity value of this Put is $3000. After deducting the $800 cost, a profit of $2200 is made. If BTC doesn't fall and even rises to $64000, this Put will return to zero and lose $800 in royalties. So buying Put is directional short selling, with the maximum loss being the premium, and the profit coming from the decline of BTC. Finally, let's talk about buying Put+selling Call=synthetic futures short selling. Assuming BTC is currently at $60000. Do two things at the same time, buy BTC at $60000 put and sell BTC at $60000 call. If BTC falls to $55000 upon expiration. Put is worth $5000. Call to zero. So in fact, buying a Put with an exercise price of $60000 represents buying the right to sell BTC at $60000 upon expiration. The more BTC falls, the more profitable this Put will be. Selling 60000 Call is selling the right to buy BTC for $60000 to someone else. After BTC rises above 60000, one has to bear the obligation to sell BTC for $60000. Therefore, the more BTC rises, the more gratitude one will receive. Putting them together, the effect is equivalent to shorting BTC at $60000. That's all for the explanation, but I guess there are still many people who are struggling with it, so dual currency is actually the solution to this problem. Of course, while solving the problem, the exchange will charge a portion of the premium, so at the same position, the returns of dual currency will be lower than options, but dual currency is indeed simpler. Selling Call is equivalent to selling BTC at a higher price. For example, the current price of BTC is $60000, and the expected price of BTC on Friday is $65000, with a royalty of $200 (100 being consumed by the exchange). So when BTC's price does not drop below $65000 at 4:00 pm Beijing time on Friday, a profit of $200 will be obtained. If it exceeds $65000, even if it reaches $70000, BTC will only be sold at $65000 and a royalty of $200 will be given. Selling PUT is the opposite, buying at a low price, which means buying BTC at a lower price. For example, personally, I am currently buying BTC by selling PUT. At the same time, the price of BTC is $60000, and I bought BTC for $59000. If the price reaches $59000 or lower, I will buy BTC at this price. Even if the price of BTC is only $50000, I can only buy it for $59000. So personally, whether it's options, dual currency, or short-term, it's safer for me. End
