Something you'll definitely find interesting in it if you're a supporter of Cardano!
Reason: They use PoS mining, which mostly addresses these issues:
First, PoS ledgers make “miners” and “token-holders” one and the same. As a result, you will never see a situation in which one side owns the currency while an opposing side secures it.
Second, transactions are final and cannot be reversed. This is achieved with what’s called “Byzantine Fault Tolerance.” Thus, even if a malicious actor could acquire the computing power to attack the network, they would still not be able to rewrite the history of the ledger. Yes, they could break in. But to no avail because they would be unable to steal a darn thing.
So Proof-of-Stake cryptos could be among the beneficiaries of any sovereign-nation threat to Bitcoin.
