It is not possible to avoid the vacancy period of only trading BTC and Ether, because everyone knows that BTC and Ether will definitely increase in value over time, but people can't wait. So when is the right time to really buy the dip and hold for several years? It's indeed difficult to wait for that moment. Moreover, aside from such a special buying point, your entry points at other times are actually not good; people just don't want to admit it and only want to make quick money. When I see small-cap coins being operated by market makers for a long-term hold of about a week, the profit timing and conditions are actually very favorable, but the defensive conditions are a bit harsh, making it more suitable for holding Spot. However, I want to use contracts to trade, which means increasing leverage, so even small funds can grow quickly. In summary, I have participated in contracts with pippin/PIEVERSE/PTB/LIGHT, and now I can truly say that I understand it and can really trade.
