According to the article, Shiba Inu remains in a pronounced downtrend as the token trades below major moving averages and struggles to sustain any recovery. Around 81.5 trillion SHIB reportedly sit on exchanges, creating heavy potential sell pressure and limiting the impact of rallies despite a modest 500 billion SHIB reduction in reserves over the last year.
