The difficulty level of the most recent block at the time of writing is more than 13 trillion. That is, the chance of a computer producing a hash below the target is 1 in 13 trillion. To put that in perspective, you are about 44,500 times more likely to win the Powerball jackpot with a single lottery ticket than you are to pick the correct hash on a single try. Fortunately, mining computer systems spit out many, many more hash possibilities than that. Nonetheless, mining for bitcoin requires massive amounts of energy and sophisticated computing rigs, but more about that later as well.
You can also accept crypto for goods or services. A growing number of online retailers are doing this for example and it falls in line similarly with being paid online with crypto for online work, as was discussed earlier. This can be risky, however, as market for crypto are still very volatile and you probably have bills and other people you need to pay using fiat currency.
Loi Luu: Revolutionary, because it takes away the middleman to attain the same purposes in transactions. Traditionally, middlemen such as banks and other forms of financial institutions are needed to ensure that a payment goes through. However, these middlemen cost money, and as a result payment transactions become unnecessarily inefficient, bloated and expensive. Additionally, having middle men introduces potential security risks and financial fraud.
In the same way that people used to (and, let’s be honest, still do) store their money in bank accounts and receive interest on their deposits, crypto interest accounts are a new and exciting model for the blockchain industry. This model is often done to in different ways, including interest-earning accounts. Some people also refer to this simply as lending out your Bitcoin. In the end, the result is the same—by transferring your Bitcoin or other cryptocurrencies to the financial service provider, you will earn interest paid in that crypto-denominated currency over time.
Let's say you had one legitimate $20 bill and one counterfeit of that same $20. If you were to try to spend both the real bill and the fake one, someone that took the trouble of looking at both of the bills' serial numbers would see that they were the same number, and thus one of them had to be false. What a bitcoin miner does is analogous to that—they check transactions to make sure that users have not illegitimately tried to spend the same bitcoin twice. This isn't a perfect analogy—we'll explain in more detail below.
Unfortunately, there are few guarantees that your money is 100% safe. The same can be said about banks but banks can often be bailed out by governments and have vast umbrella protections. Cryptocurrency holdings are known for being hacked (think on the number of markets that have been hacked over the years) and what’s more, companies in this sphere go belly up all the time.
Also, there is a growing social media & blogging platform that has skyrocketed in popularity in recent years called Steemit. It can certainly be a great way to earn cryptocurrency (STEEM) through writing. You can then trade/sell them for BTC. As of right now this is one of the best options for you to get bitcoin for free in 2020 and is especially nice for the average person just looking for some easy ways to make money online.
Lending is one of the oldest ways to use your existing money to make more money. Pretty much everyone knows that or at least has a basic understanding of how it works. If you don’t, it’s fine, here’s the basic rundown… You loan out a certain amount of money to someone for a certain reason and they pay you back with interest in a specified amount of time. The interest rates will vary depending on the market, time, and the risks involved.
Loi: Bitcoin itself is not actually being exploited, it’s is the exchanges and end-user wallets that interact with bitcoin that are being exploited by hackers and what you read about in the news. Fundamentally, Bitcoin is decentralized and completely secure. The issue today is that most of the major exchanges for buying and selling Bitcoin exist on centralized servers, meaning all of the information for users is stored in one centralized location and prone to attack. The conundrum of this is that these exchanges would be inherently more secure if they used decentralized / blockchain technologies.
If you are good at researching and writing then you can definitely earn bitcoin using those skills. There are a lot of people out there with bitcoin related websites or other types of bitcoin businesses that need content written for various reasons, or other types of writing gigs that aren’t necessarily about crypto but will still pay you in it. Whether it is to put on their own sites/blogs, use for marketing purposes, sell to others, or whatever else — the fact is they need the content. Most people are either too busy to write it themselves, aren’t good writers, or simply don’t want to do it; so they are willing to pay good money for someone else to write it for them.
Ethereum is another use-case for a blockchain that supports the Bitcoin network, and theoretically should not really compete with Bitcoin. However, the popularity of ether has pushed it into competition with all cryptocurrencies, especially from the perspective of traders. For most of its history since the mid-2015 launch, ether has been close behind bitcoin on rankings of the top cryptocurrencies by market cap. That being said, it's important to keep in mind that the ether ecosystem is much smaller than bitcoin's: as of January 2020, ether's market cap was just under $16 billion, while bitcoin's is nearly 10 times that at more than $147 billion.
