Bloomberg ETF analyst James Seyffart suggests the market is entering an 'altcoin season,' characterized not by individual token price surges but by developments through Digital Asset Treasury Companies (DATCO). Seyffart anticipates that the upcoming wave of ETF approvals will not replicate Bitcoin's institutional success. Instead, he believes multi-asset ETFs will attract more institutional capital than single altcoin ETFs. He emphasizes that institutional investors prefer regulated products for cryptocurrency exposure, which could permanently alter the traditional altcoin rally pattern.
