Dogecoin, as one of the most representative meme tokens, has experienced explosive growth in 2021 due to its community culture and market popularity, and has become one of the highest trading volume cryptocurrencies on Robinhood. Robinhood, with its advantages of zero-commission trading and direct fiat purchases, has lowered the entry barrier for retail investors, but has also been accused by the SEC of regulatory issues and, after experiencing a series of controversies, has re-enabled DOGE deposits and withdrawals. Investors need to fully assess the platform's trading convenience, liquidity, and policy risks, and reasonably plan their DOGE investment strategy.
