How Bitcoin fights DOS attacks?

Bitcoin requires every node of the entire network to synchronize every transaction, and now it can only handle 2-3 transactions per second. If an attacker controls some bitcoin wallets and conducts a large number of high-frequency transactions, will it not hit the Bitcoin system?

The Bitcoin network often has a lot of trade jams. In fact, there have been problems with "DOS", but let's assume that they are all well-intentioned real trading needs. Have you ever wondered, if you want to plan and carry out such an "attack", how do you do it? Obviously it is impossible to find a group of Bitcoin lovers and let them use their wallets to send transactions.

If someone launches such an attack, the biggest possibility is to cause a large number of trade backlogs, forced the real trader to increase the price of miner's fees, or choose to suspend transactions and wait for the network to ease. After the transactions on the network are all processed, the attacker finds himself getting a bunch of small wallets. Then what? Blood loss.

My personal answer is that there will be no such situation with ddos. This is related to the concept of the blockchain itself: the blockchain locks/confirms the content of the previous block by the appearance of the block afterwards. These content can be individual declarations or transactional information, when you can quickly increase the area. In order to make a high-frequency transaction confirmation, you are the blockchain itself. You have exceeded 50% of your computing power. You said that bitcoin from around the world is all you can - as long as you can do it quickly. . Step back 100 million. Assuming you did it, now you are in a dilemma: You are a blockchain and you want to attack the blockchain.
