They buy in limit order. These orders do not move the market, the price goes up with the market price orders. You can also short Pnut to make a lot of money.

As seen in the chart, the number of long positions keeps increasing every hour without stopping. Everyone seems to be going long on $PNUT. With so many open long positions, it's nearly impossible for $PNUT to rise. PNUT will only start climbing again once these long positions are fully cleared out.

In these conditions, I don't recommend buying $PNUT on spot. Instead, you could consider buying once $PNUT clears out these long positions and moves to a safer zone. Of course, this is not financial advice—please do your own research.
