Não há necessidade de tocar no contrato.Por exemplo, é bom duplicar a posição curta e não há liquidação.Na actual situação do mercado, a cobertura do preço da moeda garantida também pode incorrer em encargos.

Let me show you my holdings. The principal is 100,000 RMB, and currently it's 250,000 RMB.
I have basically exchanged all of my Zen for other coins.
Below is the situation after the recent exchange; I have mostly chosen old coins that are not likely to run away due to their long history, with a small total supply that is easy to pump, and they have certain technological prospects. The strategy is to exchange the coins that have risen significantly for those that have not yet increased. Switching among a few coins makes it easy to miss out on hundredfold coins, but it also makes it easier to preserve profits. My goal isn’t a hundredfold return; tenfold is enough.
