3 Altcoins to Watch in the Second Week of October 2025

The cryptocurrency market is showing positive signs in the next few days as the US government shutdown is expected to continue. This could continue to push up the price of Bitcoin and altcoins, thereby attracting new Capital from retail investors.

BeInCrypto analyzed three altcoins that have the potential to surge in price over the next few days.

SPX6900 (SPX)

SPX is trading at $1.62, holding above the key support level of $1.58. The altcoin has surged nearly 62% over the past week, hitting a two-month high. The surge reflects renewed investor interest.

Currently, SPX is about 41% away from All-Time-High of $2.29, reached in late July. Technical indicators, especially the exponential moving Medium (EMAs), suggest sustained bullish momentum. If this strength continues, SPX could break above the $1.74 resistance level and potentially climb to $2.00 in the coming sessions.

However, market sentiment remains crucial to sustaining this rally. If investors start taking profits, SPX could fall below the $1.58 support level. A deeper correction could push the price to $1.39 or lower, weakening the bullish momentum and signaling a temporary reversal in the altcoin's uptrend.

Optimism (OP)

Optimism is preparing for a major Token Lockup this week, with 4.47 million OP Token worth over $3.28 million set to enter circulation. Historically, such events have often created selling pressure, leading to a potential short-term price drop. Traders are watching closely as the increase in supply could temporarily impact OP's price.

Despite the potential for a sell-off, technical indicators are giving mixed signals. Parabolic SAR is below the candles, suggesting that OP could maintain a consolidation between $0.76 and $0.71. This pattern suggests that buyers remain in partial control, keeping volatility limited as the market absorbs the new Token .

However, if bearish sentiment intensifies after the unlock, Optimism 's price could break below the $0.71 support. A deeper correction could push OP to $0.68 or even lower. Such a move would invalidate the short-term bullish outlook and highlight the Token 's sensitivity to market supply and demand dynamics.

Aptos (APT)

Aptos is gearing up for a major Token Lockup this week, with 11.31 million APT worth nearly $60 million entering circulation. Such events typically cause short-term volatility as supply increases, which can slow APT 's momentum and create selling pressure.

Despite this, Aptos has performed strongly, rising 24% over the past week to $5.31—a two-month high. The Chaikin Money Flow (CMF) indicator shows rising Capital inflows, signaling investor confidence. If buying continues, APT could break through $5.50 and $5.73 despite the unlock event.

However, the bullish outlook depends on sustained investor participation. If Capital flows decline, APT may struggle to maintain its current strength. A drop below $5.06 could lead to a deeper correction towards $4.79, invalidating the bullish scenario.
