Is a Coin’s Age a Factor in Its Vulnerability to a Pump and Dump?
Generally, newer coins or those that have been dormant for a long time are more vulnerable. Newer coins often have lower initial liquidity and smaller communities, making them easier to control.
Established, high-market-cap coins like Bitcoin or Ethereum are far less susceptible due to their massive liquidity and distributed ownership. The age is less important than the liquidity and market depth.
