Why is it difficult to hack a Public Blockchain?

A Public Blockchain is a decentralized system. In such a system there are multiple nodes and each node is synced with the entire Blockchain database. To hack such a system, a hacker has to alter information in all the nodes. This is practically impossible. Even if somebody is able to hack it, the value of hacked coins goes down exponentially. Due to this the return on investment becomes very low for a hacker. In a public Blockchain the cost of transaction is high because a transaction is verified by thousands of users. Due to this a hacker has to pay a large amount of money to alter such transactions.
