Tech giants (such as Meta, Google, etc.) entering the market to issue stablecoins will have a significant impact on the cryptocurrency market:

1. **Significantly increase mainstream acceptance and liquidity:** The large user base and brand trust of these giants will attract a substantial number of new users and institutional funds, greatly enhancing the popularity and market liquidity of cryptocurrencies (especially stablecoins).

2. **Enhance the credit and stability of stablecoins:** The financial strength, technological capabilities, and regulatory compliance of tech giants may make their issued stablecoins considered safer and more reliable, challenging the status of existing stablecoins (such as USDT, USDC).
