From where? As the Bitcoin price increases, more miners join the network, more honest miners cause that network to be more secure, because according to the Bitcoin consensus, if 51% of the miners are malicious, the processing of information into the network may stop or false information may be processed. Crypto-economic security. Ethereum is a blockchain that first works with this system and then switches to PoS. Here, instead of mining devices that require large processing power, tiny computers containing 32 Ether are used. In this case, electricity is saved. And in order to ensure the crypto economic security I explained above, each correct block processed into the Ethereum blockchain pays Ether to computers with 32 Ether, while in case of cheating, 32 Ether is deleted. (Slashing) This is also a crypto-economic security. If you pay attention, in both models, the increase in the price of existing currencies actually increases the security of that system. While the Bitcoin price encourages miners to join the network, the Ether price makes it difficult to attack the network. That's why Bitcoin or Ether has a price; They have the task of protecting the blockchain crypto-economically.
