The statement is strongly supported by multiple high-authority primary sources. Two separate alerts from Whale Alert, a reputable blockchain transaction tracker with a 0.95 authority rating, directly report a transfer of approximately 174 million USDC (one alert for 173,999,999 USDC and another for 174,000,000 USDC) from an "unknown wallet" to "Coinbase". This slight variation in the exact amount is negligible and both alerts confirm the core details of the statement. The claim is further corroborated by a secondary source, a Phemex news article, which explicitly reports on the same 174 million USDC transfer. The remaining sources are either completely irrelevant (currency converters, a Reddit forum, a price alert service page) or describe different, unrelated transactions (such as a 100M USDC transfer from the USDC Treasury or 300M USDC transfers *from* Coinbase). There is no conflicting evidence among the provided sources. The convergence of evidence from highly credible, primary sources makes the statement very likely to be true.
