By the way, Tether’s USDT Dominance (USDT, Orange) has fallen from 6% to 4.5% in the last three weeks. This meant that the Altcoin sector saw some capital rotation from BTC.
This was confirmed by a rebound in Altcoin Market Cap (Purple), excluding BTC and Ethereum [ETH]From more than $ 600 billion to more than $ 900 billion.
For the context, the Altcoin pump from last November was characterized by similar signals -a sharp decrease in BTC and USDT -Dominance. Simply put, the Swissblock Outlook can be validated if the trend repeats itself.
That said, it was still a solid BTC season from the moment of writing, according to the Altcoin Season Index (ASI) reading of 27.
The ASI in particular is a lagging indicator. It follows the performance of BTC against Altcoins in the last 90 days.
Nevertheless, Monero [XMR]Sky [SUI]Bittensor [TAO]and tron [TRX] BTC performed better in the same period.
The Altcoin season momentum has increased since April. However, not all altcoins will perform immediately. Focus on subsector leaders with strong basic principles could improve positioning.
