If you hold popular coins such as Dogecoin and Shib, and you don’t know when to sell, it’s actually very simple. There are two reference standards.First, when Bitcoin breaks through 90,000 US dollars, sell the altcoins in your hands. Remember! It’s 90,000 US dollars, not 100,000 US dollarsSecond, wait for a quarterly positive line with an increase of about 200%, and then you can ship.In short, it is very easy to buy the bottom, but it is really difficult to escape from the top!
