A few years later, your daughter enters college in a Ferrari and practices yachting every day. Someone even wants to marry her, all because you have made a comeback in the cryptocurrency world. In the hot summer, your 30-story apartment is as comfortable as the 22-degree mountain. Your father-in-law smiles from ear to ear every time he sees you, and he drinks top-quality red wine with breakfast. You often get together with new friends in groups of three or five, bragging about your life experiences alone. Hahaha, it should be sharing. And behind all this, it is all because of your cryptocurrency speculation.
