Today, there are no major sudden policies or events in the industry, and the market is overall in a state of oscillation and consolidation in terms of existing stock games. The core dynamics are as follows:

1. Divergence signals appear in on-chain funds
Ethereum exchange reserves continue to decline, circulating chips continue to transfer out of trading platforms, and short-term market selling pressure has eased; at the same time, stablecoins on the Binance platform show a net inflow, reflecting signs of off-exchange funds gathering strength at low levels, but the premium on compliant platforms like Coinbase remains weak, and overall institutional buying in the U.S. is cautious.

2. Technical progress updates
The Ethereum Glamsterdam upgrade is expected to land in the third quarter of 2026, with core optimizations targeting transaction processing efficiency and network capacity, but current market attention is still focused on macro liquidity levels, and this long-term positive impact has not yet reflected in the short-term price.

3. Continued macro suppression environment
Following the Federal Reserve's June meeting, hawkish expectations have not faded, and expectations for interest rate cuts this year have significantly narrowed. The 10-year U.S. Treasury yield remains high, and global risk assets are under overall pressure, with insufficient momentum for incremental off-exchange funds entering the cryptocurrency market, leading to a defensive market sentiment.

II. Mainstream cryptocurrency trend analysis

As of the afternoon of June 20, 2026, mainstream cryptocurrencies in overseas markets are experiencing narrow fluctuations, with overall declines narrowing compared to the previous day:

• Bitcoin (BTC): Consolidating around $63,100, with a 24-hour increase of about 0.6%, and an intra-day fluctuation range of $62,300-$63,400. It remains below the short-term moving average on the daily chart, with a tendency towards weak oscillation; on the four-hour level, it has found support at the lower Bollinger Band, with the $62,000 level being tested repeatedly without breaking, showing signs of stabilization in the short term, but rebound momentum is insufficient, with strong resistance at $64,500 above.

• Ethereum (ETH): Quoted around $1,705, with a slight increase of 0.05% over 24 hours, and the key support level of $1,700 temporarily held. On the technical side, the RSI has recovered to about 38, exiting the oversold zone, but it is still below the neutral line of 50, indicating limited buying recovery capability; $1,800 above is a short-term dividing line for bulls and bears, and there is dense support around $1,670 below.

• Other mainstream coins: SOL is quoted at $69.4 (down 0.1% in 24h), XRP at $1.13, DOGE at $0.083, all following the overall market with narrow fluctuations and no independent trends.

• Market structure: Bitcoin's dominance remains above 58%, with capital continuing to concentrate on leading coins, making it difficult for altcoins to see broad gains, with only a few leading players in certain sectors having structural performance opportunities.

III. Market reference operation ideas

1. Spot medium to long-term strategy

• Core positions are primarily in BTC and ETH, using a staggered accumulation model to avoid one-time full positions: BTC can accumulate in batches at the $62,000, $60,000, and $58,000 levels, and ETH can enter in batches at the $1,650, $1,500, and $1,350 levels, gradually increasing positions as prices decline.

• Altcoins are not recommended for large-scale layouts at this time, but small positions can focus on leading sectors with continuous narrative catalysts such as RWA, AI Agent, and Layer2, avoiding niche coins without fundamental support.

2. Contract short-term strategy

• BTC: The reference range for oscillation is $62,000-$64,500; if it rebounds to $64,000-$64,500 and meets resistance, light selling can be attempted, with a stop-loss set above $65,200; if it bounces back to test support at $62,200-$62,500, a light long position can be attempted, with a stop-loss below $61,800, strictly controlling position size and ensuring quick entry and exit without lingering.

• ETH: The reference range for oscillation is $1,670-$1,780; short positions can be tried near $1,750-$1,780 under resistance, and long positions can be attempted near $1,670-$1,690 with a stop-loss range of about $30, strictly adhering to stop-loss discipline.

3. Solana (SOL)
• Short-term support
◦ First support: $68
◦ Strong support: $65
• Short-term resistance
◦ First resistance: $72-$74 (recent rebound high point resistance)
◦ Strong resistance: $78
• Mid-term core levels
• Strong support: $60 (low point of this adjustment, mid-term trend support)
◦ Strong resistance: $90 (upper boundary of mid-term oscillation range)
