What to know:

  • Ethereum classic (ETC) surged 20%, leading legacy coins like litecoin (LTC), bitcoin cash (BCH), dogecoin (DOGE), and XRP (XRP), driven by capital rotation after bitcoin hit record highs.
  • Trading in ETC volume spiked 212% to $756 million, while open interest in DOGE and UNI rose sharply, suggesting heightened speculative trading.
  • A BTC breakout above $124,000 could sustain altcoin momentum, while a drop below $110,000 risks triggering leveraged liquidations and widespread sell-offs.

The highly-anticipated altcoin season is finally here. After bitcoin broke record highs last week and consolidated this week, the way opened for capital to rotate into the more speculative altcoin market.

Friday's top performers are known as dinosaur coins, many of which were created before the 2017 bull market.

leads the pack with a 24-hour surge of 20% after breaking through the $20.27 level of resistance. It still faces a stern test at $25.00, a level it rejected exactly one year ago before plummeting to $15.80.

ETC's growing popularity is reflected in its trading volume. That tripled to $756 million, showing the move is backed by traders who are rolling capital from sector to sector in true "altcoin season" style.

, , and of course XRP also posted notable gains. And all rose to stardom as retail investors poured capital into the 2017 cycle.

LTC is up in part because of MEI Pharma's $100 million LTC fund with the project's founder, Charlie Lee, taking a board seat. But it's also due to a general rotation into legacy coins that stuttered during this week's ferocious altcoin move.

Uniswap , which was actually released slightly later than the others, in 2020, also climbed 20%, and as volume topped $1.7 billion — a 70% increase.

It is now trading above the $8.11 and $10.33 levels of resistance as it looks to move up towards $12.09, a level that caused several rejections during the middle of last year.

What does Friday's move mean?

The rotation into dinosaur coins can be looked at one of two ways. Either it is a bullish scenario in which traders are flipping their gains and moving methodically from sector to sector, or it is the early etchings of a cycle high, with traders attempting to squeeze the final scraps of profit before a the market enters a correction.

There are several technical indicators that first, bullish, scenario is the most likely, including a series of breakouts above months-old levels of resistance. If, however, bitcoin tumbles below $110,000 altcoins will suffer a complete wipeout.

Open interest on several altcoins suggests the recent move has been backed with leverage. Dogecoin open interest is up at $2 billion, a 30% rise in 24 hours, while uniswap's is up by 35% to $389 million, Coinalyze data shows.

This means that if the market experiences a broader sell-off, leveraged altcoin positions will unwind, leading to liquidations and subsequent pressure to sell. Coupled with the reduced liquidity and lower market depth of altcoins, several tokens could face a decline in excess of 10%.

The ideal scenario for altcoins is bitcoin climbing above the $124,000, a level of resistance, and moving higher before another period of consolidation. That would allow capital to rotate without the risk of an immediate correction.

Japan’s Higher Rates Puts Bitcoin in the Crosshairs of a Yen Carry Unwind

A stronger yen typically coincides with de-risking across macro portfolios, and that dynamic could tighten liquidity conditions that recently helped bitcoin rebound from November’s lows.

O que saber:

  • The Bank of Japan is expected to raise interest rates to 0.75% at its December meeting, the highest since 1995, affecting global markets including cryptocurrencies.
  • A stronger yen could lead to de-risking in macro portfolios, impacting liquidity conditions that have supported bitcoin's recent recovery.
  • Governor Kazuo Ueda indicated a high probability of a rate hike, with officials prepared for further tightening if their economic outlook supports it.
