If someone invests in their own wealth to buy a single coin, I think it's dangerous because we're going to be dependent on a single, high-risk, high-risk coin.
If you invest in a small amount of money for a coin then you are likely to make a higher profit. If you invest in a small amount of money for many types of coin then you are likely to make a lower profit but safer. However, no one knows how much profit or loss, so you should know before investing.
