BTC is at $44,537 at the time I am writing this pok. By december 31st, it should have pass $50,000 multiple times during the year, but I don't think it will have reached $100,000 yet.
So that's my prediction: BTC over $50,000 but under $100,000 by the end of 2021.
A pok's hash
is a fingerprint of the pok content.
A specific text will always have the same fingerprint.
It is however impossible to guess the pok content from it.
sha1, sha256 and sha512 are different algorithms used to compute the hashes below.
The hashes were published as soon as the pok got created, proving that the author hasn't altered the text content in between.
