5 Altseason Indicators Flash Green—Time to Pile Into Altcoins?

All systems go? Bitcoin dominance wobbles as Ethereum and mid-caps surge—classic altcoin rally precursors. Here’s what’s ticking the boxes:

• BTC Dominance Cracks: King crypto’s market share slips below 45%, historically altcoins’ cue to run.

• ETH/BTC Breakout: The flippening narrative gets fresh oxygen with Ethereum outpacing Bitcoin for 3 straight weeks.

• Fear & Greed Hits 80: Retail FOMO meter pegged at ’max greed’—because nothing screams ’top’ like your barista explaining cross-chain bridges.

• Stablecoin Inflows Spike: $2B floods into USDT/USDC last week—dry powder waiting to chase alpha.

• Meme Coins Wake Up: Dogwifhat and friends post 3-digit gains, because apparently ’utility’ is just a six-letter word.

Wall Street’s still arguing about Fed rates while degens front-run the liquidity wave. Just remember: every ’supercycle’ looks genius until the leverage longs implode.

Altseason Yet?

Firstly, the narrative around bitcoin has changed, and it is no longer seen as speculative but as a macro hedge and store of value, backed by institutions and stock markets, and a geopolitical asset for countries facing inflation.

Altcoins, especially major layer-1s like ethereum and Solana, are now viewed as technology platforms, and not “Bitcoin alternatives.”

Add to those two narratives an increase in global liquidity, expanding stablecoin supply, altseason index showing bullish divergence, and retail index near bottom — all of which have historically preceded major altcoin runs.

According to CoinMarketCap’s Altseason Index, it is still Bitcoin season with a rating of 26. However, it has bounced off a low of 15 earlier this month when Ethereum started to move.

CryptoRank’s Altcoin Index shows a similar pattern, with it moving from mid-teens to 27 at the time of writing.

Additionally, the ETH/BTC ratio, which is a measure of Ether prices in terms of Bitcoin, has bounced off a 5-year low of 0.018 to 0.025 over the past couple of weeks.

Meanwhile, Bitcoin dominance has fallen from a 4-year high of 65.4% to 62% in the past week, according to Tradingview.

Altcoin Golden Cross

On May 14, Web3 growth manager Cas Abbé observed the confirmation of an altcoin market capitalization daily golden cross. It happened last time in October 2024, which led to a mini altseason, he added, before cautioning that there could be more sideways action before any major upward momentum.

Altcoin MCap daily golden cross has now been confirmed

It happened last time in October 2024, which led to a mini Altseason.

But no mistake, a golden cross doesn’t immediately start a rally.

In 2024, Alts went sideways for 3-4 weeks before going on a parabolic run.… pic.twitter.com/O4Hv6TOmqk

Meanwhile, analyst ‘Ash Crypto’ told his 1.8 million X followers that altseason was coming after observing Ethereum gaining 30% over the past week while Bitcoin has made less than 3%.

Crypto markets have cooled a little over the past 24 hours, and altcoins are generally mixed. Those still in the green on Friday morning include Binance Coin, Tron, Sui, and Hyperliquid.
