What is this? Why is the altcoin rising so sharply. A market value of 25 billion US dollars is really hard to sell, and if you buy it, you might end up with 250. Circle's valuation at 20% to 30% on Coinbase is reasonable, and earning $500 million annually is not a problem. Based on a 30 times P/E ratio of $15 billion, it is more appropriate to wait until below $15 billion before buying. Most investments are made at valuations of $4.5 billion or higher, with a minimum book return of five times.
