你如何交易数字 options?
Touted, hyped and bannered as the new world money, cryptocurrencies have been blowing hot and changing how transactions are done in the real world. In a period of a few years, cryptocurrencies have grown from mere digital novelties into a trillion-dollar industry. Among its pillars is how it makes payments more effective than what it is today.
Cryptocurrencies ride on the waves of blockchain technology. If you are unfamiliar with the term, blockchain is the digital, distributed, and decentralised ledger that underlies virtual tokens, and is responsible for recording transactions without the need for a financial intermediary, such as a bank.
Blockchain is, in many ways, labelled as a huge game-changer and it’s the only reason we are raving about cryptocurrencies these days. However, a blockchain network is only as good as its ability to process, validate, and settle transactions efficiently. In reality, though many companies are growing to accept cryptocurrencies such as Bitcoin as payment methods. This, in turn, restricts how and where you can spend your money unlike using a debit/credit card.How cryptocurrency payments work
Transactions done in traditional banks have a time frame. Transferring money can take a few minutes to get to the recipient, but sometimes could be longer. Blockchain technology is meant to make such transactions easier and faster in privatising items anywhere they are 你如何交易数字 options? collected.
Transaction time impacts the speed of receiving cryptocurrency. Sometimes, in 2017, it took an average time of 78 minutes to confirm a Bitcoin transaction. On the Bitcoin network today, the average confirmation time for a BTC payment is about 10 minutes. Nonetheless, transaction times can vary so much due to factors, such as the total network activity, hash rate, block time and size, and transaction fees.
If the 你如何交易数字 options? Bitcoin network is congested, there will be a backlog of transactions in the mempool, which is a record of all Bitcoin transactions that have not yet been validated by a miner 你如何交易数字 options? and added to the next block on the blockchain
In order for transactions to go through faster, users have to pay more transaction fees. This happened April 2021, where average Bitcoin transaction fees reached $59, according to CoinMarket. Credit card transactions, on the other hand, only take a few seconds to complete.
Furthermore, on Ethereum, users pay a base fee to have their transactions verified by other users, known as miners. The 你如何交易数字 options? average transaction fee on the Ethereum network rose to as high as $63 in November. That was its second-highest level ever, behind May’s record high of $70. There’s not much mercy for the small fries on that ETH network.
Another look at the ineffectiveness of cryptocurrency payment is the fact that payments made by mistake cannot be reversed like traditional banking payment systems. Bitcoin transactions are anonymous and unregulated, which breeds the disadvantage of lack of security.
Likewise, all transactions completed through Bitcoin are irreversible and final, so pretty much zilch can be done if the wrong amount is sent or if it’s sent to the wrong recipient. In traditional banking systems, payment can 你如何交易数字 options? be reversed if the wrong sum is sent or sent to the wrong recipient. This amount of accountability makes payment less fraudulent and traceable.
That said, Ethereum 2.0 is an upgrade to the Ethereum blockchain which aims to enhance the speed, efficiency, and scalability of the Ethereum network so that it can process more transactions and reduce transaction fees.
Ultimately, people believe that Bitcoin has value as wealth storage, 你如何交易数字 options? similar to digital gold and that second-layer solutions — an additional framework that sits on top of the present blockchain — might improve its speed and make it more practical for use as an effective payment option.
In the same vein, many still hold the notion that cryptocurrencies will be the new financial system. While that might be possible, there is 你如何交易数字 options? still a lot that needs to be put in place to mitigate cost on the part of the sender and the receiver.
In the meantime, one may hope that, at some point, in the blockchain technology upgrade, there might be a zero withdrawal fee which would ensure everyone has equal opportunity to be part of this financial ecosystem and fully enjoy purchases in the real world.

2022入門選擇權教學》買權賣權是什麼？選擇權基本運作與策略運用
賣出16400Call，表示認為大盤不會漲超過16400，當大盤低於16400都能賺錢，如果漲到16400以上則要開始賠錢給買方，橘色區域是「獲利遞減區」，漲過16420則開始虧損，為什麼是16420才開始虧損？由於賣方是先賣出才收錢，先收了20點，一旦漲超過16400，大盤每漲1點要賠給買方1點，會先從買方那裡收到的20點開始賠，也就是拿買方自己的錢賠給他，若是把收到的錢賠完才會賠到本金。而光是這一點「買方vs賣方」的勝率就差很多了，買方要花錢買機會，還要漲到把花掉的錢賺回來才算是真獲利；賣方則是先收錢，若漲到16400，可以先拿收到的錢賠給對方。
買選擇權要先花錢，賣選擇權可以先收錢！
教你看懂選擇權策略圖，掌握賣方損益計算！
裸賣Call損益計算方式
「裸賣」顧名思義就是只賣Call ，但沒做價差保護。賣一口16400Call ，收到20點權利金。從下圖來看，橫軸是大盤點位，縱軸是損益變化：
我建議千萬不要裸賣CALL，不僅獲利有限、風險無限，還要押很多保證金，大盤上漲會持續虧損，很可能血本無歸，必須用價差單策略控制風險。
- 狀況1：賣16400的call，當初跟買方收20點權利金，結算後大盤收盤在16300，選擇權價值為0點，賣方需花0點買回來平倉，則獲利20–0=20點。
- 狀況2：賣16400的call，當初跟買方收20點權利金，結算後大盤收盤在16410，因為大盤漲的比16400call的履約價還要高10點，所以賣方要賠給買方10點。但是當初賣出收的權利金是20點，所以賣方還是獲利，獲利20–10=10點。
裸賣PUT損益計算方式
裸賣Put 卻沒有做價差保護，當你賣一口12200Put 收到20點權利金，該如何計算損平點呢？以下帶你一起看選擇權策略圖：
為什麼損平點是12180呢？因為賣出Put ，當跌破履約價，每跌1點就要賠給買方1點，跌到12180要賠20點，不過一開始權利金就先收了20點，所以拿權利金去賠給買方。賣出Put 的履約價減掉收到的權利金等於損平點位。
- 當價平和高、震幅低：使用中立策略Iron Condor，維持中立賺取時間價值。台股2020年之前適合。
- 當價平和高、震幅高：適合使用大區間進場策略，賺波動價值。台股2021年走勢適合。
- 當價平和低、震幅高：雙買+小台進場策略可以大幅交易提昇盈虧比。台股2021年Q3～2022年Q2適合。
- 偏多策略 跨合約賣權多頭搭配賣CALL 策略。時機簡單明瞭新手適用。
