Dogecoin was launched in 2013 and was initially viewed as a Bitcoin imitator. Today, its price has skyrocketed from $0.00026 to $0.096, and driven by celebrity endorsements, an initial investment of $10,000 has grown to $3.69 million. Unlike Bitcoin and Litecoin, Dogecoin has no supply cap, with a circulation of approximately 153 billion coins, and lacks native smart contract support. Its future faces challenges from oversupply and insufficient developer participation, but a spot ETF approved by the Securities and Exchange Commission (SEC) could potentially serve as a catalyst for development if it attracts more institutional investment.
