The Taihuttus declined to share with CNBC the current dollar amount of their crypto investment in aggregate. But Taihuttu did disclose that they had fully bought back into bitcoin by the time the coin surpassed the $19,000 price threshold, so they're "not doing so bad." Bitcoin purpose Unfortunately the SHA-256 hash works on a block of 512 bits, but the Bitcoin block header is more than 512 bits. Thus, a second set of 64 SHA-256 hash rounds is required on the second half of the Bitcoin block. Next, Bitcoin uses double-SHA-256, so a second application of SHA-256 (64 rounds) is done to the result. Adding this up, hashing an arbitrary Bitcoin block takes 192 rounds in total. However there is a shortcut. Mining involves hashing the same block over and over, just changing the nonce which appears in the second half of the block. Thus, mining can reuse the result of hashing the first 512 bits, and hashing a Bitcoin block typically only requires 128 rounds.

Bitcoin’s difficulty is the measure of how hard it is to find a block while mining Bitcoin’s blockchain. Bitcoin's difficulty is a bespoke scoring system that is measured on a scale of 1 to (theoretically) infinity (for e.g., Bitcoin began at a difficulty of 1, but at the time of writing, Bitcoin's difficulty is 27.55 trillion).
