Growing concerns about huge energy consumption have led to a ban on bitcoin mining in many countries that are considered welcoming environments for activity, meaning hotspots are constantly changing. On March 6, 2014, Bangko Sentral ng Pilipinas (BSP) issued a statement on the risks associated with trading and using Bitcoin. Recently, virtual currencies have been legalized and cryptocurrency exchanges are now regulated by the Central Bank of the Philippines (Bangko Sentral ng Pilipinas) under Circular 944. However, Bitcoin and other “virtual currencies” are not recognized as currency by the BSP because “they are neither issued nor guaranteed by a central bank, nor backed by a commodity”.  Although miners may choose to go alone, membership in a pool offers them immense benefits. Pooled mining uses shared hardware capabilities and allows miners to spread risk and energy costs while increasing their bets, discovering a block, and earning a block reward. It is also relatively cheaper to join a mining pool because the capital requirements are spread among several miners. Although mining revenues are shared among miners, so lower payouts, they are stable thanks to more profitable participations. Most people think that crypto mining is simply a way to create new coins. However, cryptocurrency mining also involves validating cryptocurrency transactions on a blockchain network and adding them to a distributed ledger. More importantly, crypto mining prevents the double spending of digital currency on a distributed network. The screenshot below, from the Blockchain.info website, could help you gather all this information at a glance.
You`re looking at a summary of everything that happened when block #490163 was dismantled. The nonce that generated the “winning” hash was 731511405. The target hash is displayed at the top. The term “relayed by Antpool” refers to the fact that this particular block has been completed by AntPool, one of the most successful mining pools (more on mining pools below). Although crypto is not banned in Russia, until recently there was a conflict against its use. Now he is seen as a savior to help the country circumvent harsh Western financial sanctions. 5. In February 2021, the Central Bank of Nigeria issued a circular informing Nigeria`s financial institutions that the continuation of its January 2017 circular would prohibit cryptocurrency trading or facilitate its payment and result in a hefty penalty.  Aside from the fact that Bitcoin is illegal in a country, there are usually not many reasons why a country wants a specific mining ban. Nepal Rastra Bank declared Bitcoin illegal in August 2017. As of August 2018, the US FinCEN had received more than 1,500 SARs per month with cryptocurrencies.
 Seventeen other countries have similar anti-money laundering requirements.  For example, the average ASIC miner consumes about 72 terawatts of energy to create a bitcoin in about ten minutes. These numbers continue to change as technology advances and the difficulty of mining increases. The Central Bank of Russia and Rosfinmonitoring, in their calls for information, have repeatedly warned Russian citizens that all cryptocurrency operations are speculative and carry a high risk of depreciation. The Central Bank of Russia states: “Most cryptocurrency operations are carried out outside the legal regulations of the Russian Federation and most other states. Cryptocurrencies are not guaranteed or provided by the Bank of Russia.  For example, at the end of August 2022, according to data from Markets Insider, Bitcoin`s price was around $20,000, which would bring the mining incentive to around $125,000. At the beginning of the year, it was close to $48,000, which would bring the mining reward to about $300,000. Cryptocurrency mining is tedious, expensive, and only sporadically rewarded. Nevertheless, mining has a magnetic appeal for many investors interested in cryptocurrency, as miners are rewarded for their work with crypto tokens.
Perhaps that`s because entrepreneurs view mining as a penny from heaven, as California gold prospectors did in 1849. And if you`re tech-savvy, why not you? “For most people living in the U.S. and Western Europe, where the cost of electricity per unit is high, it`s hard to operate, but not impossible,” Spanos says. People living in Asia have access to much cheaper electricity, but they are less likely to be able to afford the initial cost of mining bitcoins. Although it is not officially banned, the Bank of Tanzania advises against using cryptocurrency, pointing out that the Tanzanian shilling is the only acceptable legal tender.   Bitcoin mining has also caused some controversy due to concerns about its impact on the environment. Some industry observers have estimated that this activity has a carbon footprint similar to that of a small country. Russian President Vladimir Putin has repeatedly linked cryptocurrency to criminal activities, paying particular attention to cross-border crypto transactions. As with physical currencies, when a member spends cryptocurrency, the digital ledger must be updated by debiting one account and crediting it to the other. However, the challenge of a digital currency is that digital platforms can be easily manipulated. Bitcoin`s distributed ledger therefore only allows verified miners to update transactions on the digital ledger.
This gives miners the added responsibility of protecting the network from double spending. Egypt`s Dar al-Ifta, the country`s main Islamic advisory body, issued a religious decree in 2018 classifying bitcoin transactions as “haram,” which is prohibited by Islamic law. Although non-binding, Egypt`s banking laws were strengthened in September 2020 to prevent trading or promoting cryptos without a central bank license. Bitcoin mining is basically programming computers to solve complex mathematical problems in order to verify transactions on a network. When the solution is resolved, it secures the network and generates a new bit. There is also time pressure when it comes to Bitcoin mining, as the resource is limited. The evasive and alleged creator, Satoshi Nakamoto, instilled a cap of 21 million Bitcoin in the creation of the source code. This means that as the size and efficiency of the Bitcoin mining industry increases, the mining work will become more difficult. This also explains why the crypto mining industry is based on Bitcoin and not, for example, Ethereum or tenders. Thus, finding the right location with electricity costs below less than 10 cents per kWh will help keep a Bitcoin mining company profitable. The race to solve these increasingly difficult cryptographic puzzles requires significant amounts of energy.
