Coinranking.com VS Proof of existence

I'm fairly new to the crypto world and I've been reading about the PulseChain, PulseX and HEX.I've read that somewhere in its time HEX did 10000x, but I can't find reliable data on the high and low prices of this coin, since the information differs in every site I've been (hex.com, coinranking.com, coinmarketcap.com ) . Can someone explain to me why they are saying HEX did a 10000x? Where can I get the most... Source: over 1 year ago

- Shiba INU: I don't get it. The description on coinranking.com literally just says the coin was created to give coins to Vitalik. Why is its value not zero? Source: over 2 years ago

Not sure which site you are using. nomics.com and coinranking.com both have HEX well above SHIB. Source: over 2 years ago

Write down everything you remember while it is still fresh, including all BTC addresses. You can even store a hash of your notes in the blockchain as proof of existence. Source: about 1 year ago

If that's not enough, you could publish a hash. Proof of Existence is a service that adds it to the blockchain so you can always prove it, but realistically that's overkill and I'm sure sticking it on Google Drive would be enough. Source: over 1 year ago

Bitcoin has proofofexistence.com. It hashes a file via the browser and stores the result in OP_RETURN. The current fee is around $7, which is no longer practical. Source: almost 2 years ago

Proof Of Existence is a service for this. You take the hash of the photo, then when you're picking random numbers to mine bitcoin, pick numbers that start with that. Once you've successfully mined a block, that number will be stored in the blockchain. Source: over 2 years ago
