Many people see some small cryptocurrencies and want to double their investment quickly, but first they need to be clear—these assets are very likely scams or clone coins, with risks so high they can easily wipe out your capital at any moment. If you really want to participate, never go all-in and gamble everything.

Some consider shorting these kinds of coins, which is a good idea in theory, but you need to be cautious of several pitfalls during operation. First, only use small funds to influence the market; don’t expect to get rich overnight. Don’t be too greedy with leverage either—more than 5x is very dangerous, and liquidation can happen faster than you imagine. Setting strict stop-losses is essential—once the market reverses, you must cut your losses quickly.

Another easily overlooked detail: shorting requires continuously paying funding rates to the long side. The longer the position is held, the higher the cost, and this money can easily eat into your profits over time.

Speaking of which, those so-called "guaranteed profit" signals on social media are basically tricks spread by market manipulators. When they shout "Buy XXX," they’re actually setting up the opposing side. When retail traders follow and buy in, they then reverse their position to profit from the move. This kind of scheme happens year after year—be more cautious.
