Is this evidence of Bitcoin going mainstream?
Would an ATH in addresses lead to a new ATH in the price?
There's no correlation between them and the bitcoin price, and bitcoin adoption. Every user has made thousands of addresses
Maybe these empty BTC address will soon be filled with BTC also. I heard that when you do an transaction, the btc address will have a high possibility that it can be hacked thru quantum computer due to the exposure of the public key when making transaction.
You're reading too much fantasy stories. Bitcoin cracking with quantum is not even possible as of now even the one google built as of todate.
