Matthew Sigel, Head of Digital Assets at VanEck, has warned that several low-market-cap companies, particularly micro-cap firms listed on Nasdaq, are likely orchestrating pump-and-dump schemes by announcing plans to raise hundreds of millions of dollars to purchase cryptocurrencies such as XRP and Solana. One company with a $16 million market capitalization recently disclosed intentions to raise $500 million to buy XRP tokens, raising concerns about the legitimacy of these fundraising efforts. Additionally, there is caution against buying NAKA tokens at current prices due to high post-merge selling pressure, with a supply of 9 billion tokens compared to only a few million in daily trading volume, indicating potential risks for investors.
