A prominent crypto trader believes altcoins might be in a prime accumulation phase, pointing out a buy signal that hasn’t triggered so low in over three years.

“Altcoins currently at the ‘sell your house to buy more’ level,” crypto trader Luke Martin told his 331,500 X followers in an Aug. 28 post .

The “Alts buy signal” chart gives traders an indication when the overall altcoin market is at a buy, based on historical data. 

Martin said that when Bitcoin ( BTC ) was at this level last, in the summer of 2020, the price went sixfold over the second half of the year.

“Price went vertical from 10k to 60k over the next 6 months,” Martin wrote.

Meanwhile, pseudonymous crypto trader Mags pointed out that the “altcoin market cap is forming a falling wedge pattern, which is a bullish continuation pattern.”

At the time of publication, the altcoin total market cap is $195.07 billion, per TradingView. MN Consultancy founder Michael van de Poppe highlighted that it is “still 47% down from the highs” in an Aug. 25 X post .

The altcoin market cap peaked at $446.85 billion in November 2021.

“Breakout is going to trigger a nice upside rally,” Mags added.
