Proof of Work vs Proof of Stake: Conclusion

Thanks to a PoS system validators do not have to use their computing power because the only factors that influence their chances are the total number of their own coins and the current complexity of the network.

So this possible future switch from PoW to PoS may provide the following benefits:

1. Energy savings;
2. A safer network as attacks become more expensive: if a hacker would like to buy 51% of the total number of coins, the market reacts by the fast price appreciation.
