Anything related to finance is inseparable from liquidity and capital pool. Whether it is cryptocurrency, stock trading, or fund trading, the essence remains the same. Everything can be a Ponzi scheme. If you want to make money in the cryptocurrency circle relying solely on luck, you will definitely lose a lot. As long as you see through the operating mechanism of the plate and understand the relationship between liquidity and capital pool, you will be invincible in any project. A lot of people say, that's not right, I'm a serious cryptocurrency trader, I don't play the kind of game that requires promotion or forced deposits to earn interest. I just buy coins, buy low and sell high. In fact, this is also a kind of plate. Here I would like to give you some popular science about the famous Ponzi scheme. The three plates refer to the dividend plate, the mutual aid plate and the split plate. Among them, the dividend plate and the mutual aid plate are easier to distinguish and classify, because the dividend plate, as the name implies, will form a pool of funds, and generally funds are not allowed to flow in and out freely. It develops in the way of absorbing deposits, and generally promises a fixed or range of returns. Mutual aid plates are to transfer money to each other to form a cash flow mismatch. Generally, there is no pool of funds, and most of them do not allow free entry and exit. Generally, they promise a rate of return. The split plate continuously splits assets into different targets to form a pool of funds, and generally allows free entry and exit, but no rate of return is given. Now that you have understood what the Three Plate Theory is, here is a question for you to think about: which of the three plates do you think $BTC , meme $DOGE , and $ETH belong to, or which is the most profitable project you have ever played, and which of the three plates does it belong to.
