It is more worry-free to use Stud Copycat. If you spend acceptable funds, the bear market will either return to zero or the bull market will be dozens of times higher. Unlike the contract, you are afraid every day, and you are afraid of the exchange pulling the plug, and you are afraid of Gouzhuang inserting needles, and you will not be able to eat well every day. Can't sleep well
What kind of copycats do you guys have?
