An anonymous Ethereum investor has made a profit of $688,000 in less than two days through a strategic crypto maneuver. The investor purchased 20.7 billion RefundCoin (RFD), a recently-introduced Ethereum-based meme coin, using 55 ETH ($100,000) and sold off their entire RFD holdings today for 435 ETH ($788,000).

The trade has elicited varied reactions from the broader crypto community, with some considering it a classic example of high-risk, high-reward trading while others believe it could be a case of insider trading involving RFD.

Investors are advised to remain cautious when making trade decisions, as meme coins pose high risks due to their nascence and unknown tokenomics.
