Well I was going to give this user a chance to edit his post to put a source in it but seeing that he plagiarized multiple posts he's beyond saving.

jamil10 Banned!Plagiarized:Bitcoin was the pioneer in mining when it first entered service in 2008, and it is still one of the most popular coins among crypto miners.
Mining fulfills several essential functions: it ensures the security of the Bitcoin network and it processes transactions. In addition, it allows participants to win BTC as a reward.
Bitcoin hash function
To operate a block, participants must solve cryptographic hash problems. This is called "hashing".
Bitcoin relies on a specific hash function called SHA-256. This is only important insofar as the nature of SHA-256 has led to an arms race for increasingly powerful computer chips, specially designed for bitcoin mining.
It is no longer possible to mine Bitcoin for profit using commercially available computer hardware, such as a GPU or CPU. To be competitive, minors must use a device called ASIC (application-specific integrated circuit), which is able to quickly resolve problems related to SHA-256. One of the most popular ASIC lines is the Bitmain Antminer.
Bitmain Antminer S19 Pro
Bitmain's S19 Pro Anteater
Bitcoin could abandon SHA-256 and adopt an alternative to resist the dominance of ASIC, but it is unlikely to do so. Critics such as Cobra and BTC POW Upgrade have advocated changes to Bitcoin's mining protocol, but have failed to gain ground.
Profitability of ASICs
There are several different models of ASIC mining devices on the market. The most profitable ASICs have a high hash rate in terachas (TH / s) and low power consumption in watts (W). Keep in mind that hashrate and energy efficiency are changing rapidly as new, more efficient ASICs are brought to market.
According to F2Pool, these ASICs are among the most profitable:
Antminer S19 Pro, 110 TH / s, 3250 W, sold at 2,900
Whatsminer M30S ++, 112TH / s, 3472 W, sold for 1,800
Hummer Miner H9 Pro, 84TH / s, 3360 W, sold at 1600
Canaan Avalon 1166, 68 TH / s, 3196 W, price unknown
INNOSILICON T3 +, 67 TH / s, 3300 W, sold for 2000
There are also consumer devices like the Coinmine One. However, these plug-and-play mining devices are unlikely to generate profits.
Original:0.19.0 .1 release notes
Bitcoin Core version 0.19.0.1 is available at
https://bitcoincore.org/bin/bitcoin-core-0.19.0.1/If you are running an older version, shut it down. Wait for a complete shutdown (this may take a few minutes on older versions), then run the installer on Windows, overwrite / Applications / Bitcoin-Qt on Mac, bitcoind / bitcoin on Linux Overwrite -qt.
It is possible to upgrade directly from a version of Bitcoin Core that has reached EOL, but it can be time consuming if you need to migrate your datadir. Older versions of Bitcoin Core wallets are generally supported.
compatibility
Bitcoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.10 and above, and Windows 7 and above. We do not recommend using Bitcoin Core on unsupported systems.
Bitcoin Core should work on most other Unix-like systems, but it hasn't been tested that often on those environments.
Since 0.17.0, macOS below 10.10 is no longer supported. 0.17.0 is built using Qt 5.9.x, but it doesn't support macOS below 10.10. Furthermore, the appearance of Bitcoin Core does not change when dark mode is enabled on macOS.
Users running macOS Catalina will have to "right click" and select "Open" to open Bitcoin Core .dmg. This is due to new signing requirements imposed by Apple, which the Bitcoin Core project has not yet followed.
