Bitcoin (BTC), Ethereum (ETH), Solana (SOL), and Ripple (XRP) price have made big gains in September, which have pushed the total crypto market cap from $2.62 trillion on September 1 to $2.87 trillion at the time of writing.

Analysts are now predicting the prices at which the four biggest cryptos by market cap will close on September 30, as the fear and greed index reading of 70 shows that the market remains in “greed” territory.

BTC price is on track to record its fourth straight September in the green, with month-to-date returns at 7.37%.

Analyst Philakone on X notes that BTC price remains above the 50-day and the 200-day SMAs, suggesting that the daily trend remains bullish. He notes that the resistance for Bitcoin now lies at $87,385.

Analyst Martini Guy also notes that if Bitcoin price can reclaim the $85,000 price, it could move back towards $87K.

A recent CoinGape Bitcoin price analysis also noted that Bitcoin price remained within a bull flag pattern on the one-day chart and could move towards $87,000 by month-end if support holds.

Ethereum price is up by 9.25% month-to-date, with this gain boding well for other altcoins including XRP and Solana.

Analyst Alex Marzell now notes that Ethereum price could continue climbing towards $2,900, where there is a high liquidity cluster.

Analyst Daan Crypto also notes that Ethereum price is facing resistance at $2,800. If ETH price can move above this resistance, the analyst says it could cause a “big move.”

Ethereum price is also defending support at the 200-week EMA, as earlier reported by CoinGape, suggesting that the long-term trend remains bullish and more gains could occur by month end.

SOL price traded at $122 at the time of writing after posting an intraday gain of 1.22%. Analyst Alaoui Capital now says Solana’s uptrend could extend towards $130 after the price broke from consolidation.

The analyst also attributed SOL price gains to inflows to ETFs that have amassed 1.475 million SOL in two weeks.

Analyst Apex Gotu also notes that SOL has a liquidity magnet above price at between $125 and $130 that could cause another bullish Solana price forecast .

XRP price is up by 7.9% in one month, and analyst Diana on X now notes that the uptrend might extend until $1.70.

The analyst noted that XRP price was rejected at $1.61, but the momentum is now turning bullish on the four-hour chart. If XRP price breaks resistance at $1.61, the move to $1.70 could occur.

The analyst’s bullish outlook comes amid a surge in inflows to XRP ETFs to $117.44 million in September 2026 alone.

The ongoing upgrades on the XRP Ledger could also aid more gains for the XRP price.

Therefore, as the crypto market comes near to closing the month of September in the green, BTC, ETH, SOL, and XRP price are expected to inch higher. But besides technical outlooks, geopolitics and the upcoming PCE Inflation release could affect price movements.
