Relative strength amidst major sell-offs

While watching the market, I noticed an interesting phenomenon: after the FOMC meeting, most major asset classes rallied, but Bitcoin and Ethereum surged with the sluggishness of constipation, whereas some mainstream altcoins showed exceptional strength $ZEC $Hype $Uni etc. The only explanation is the ETFs. From last week until now, there has been a net outflow of $1 billion. Since the 15th, there has been a daily net outflow of over $200 million. Americans are acting like maniacs; every day, prices rise before the market opens in the daytime, only to be smashed upon opening. Every time Bitcoin rises by a few hundred dollars, it gets sold off hard. The candlestick charts look like an electrocardiogram—it's disgusting.
