Today's altcoin-wide pump 'Crime Pump' once again proves my point. The essence of the rise is still contract-driven. Too many 'smart guys' chose to short altcoins with low leverage for a long time to hedge against major coin trends, only to end up becoming the counterparty for wild whales' OI, getting wiped out in one move. In the crypto world, there's no such thing as a 'safe low-leverage hedge.' Essentially, almost all coins are assets that move in the same direction. When it comes to specific coins, if spot liquidity is good, they'll dump the spot market; if spot liquidity is poor, it depends on which side has the larger OI. Whales want to make money, so the safest side is always the one with fewer people. But which side has fewer people is a dynamic question—the tides of attack and defense are ever-changing. So, if you're not a professional trader, the only solution is to reduce your exposure time, but increase leverage during that exposure and set a stop-loss. Get in and get out quickly. If you can win, go for it. Try to close your positions before going to sleep.
