Why does changing a single character make the entire hash look completely different?
First, the definition: It’s difficult to work backward from a hash value to the original input, and difficult to find two different inputs that produce the same hash value.
The logic behind it: Hashing is not encryption. Encrypted data can be restored using a key, but hashing is one-way—you can’t recover the original content from the hash value.
Mining $BTC is essentially repeatedly calculating SHA-256 hashes to find a result that meets the difficulty requirements. Current price: 82860.93.
Market conditions are always uncertain, so think ahead about what to do if your judgment turns out to be wrong.
