It's becoming increasingly difficult for retail investors to make money in virtual currencies, as most altcoins are highly controlled by project managers and platform operators. Moreover, the holdings data of project teams and retail investors on platforms is clear at a glance, allowing the manipulators to arbitrarily raise or lower prices to harvest retail investors, especially in contracts. Additionally, there are funding rates that can also harvest retail investors, making it easy for them to get trapped when buying high or fall into traps when shorting. This kind of unregulated and barbaric manipulation behavior will ultimately severely damage the survival environment for virtual currency investments, making it no different from a casino run by manipulators, and it can no longer be considered an investment.
