TLDR:Bitcoin must hold $81,000, the lower boundary of its daily rising channel, to target $84,000 and $86,500.A break below $81,000 would shift Bitcoin’s focus to $76,000 as the next downside level to watch. Ethereum must hold $2,350 on a daily close to target $2,700 and $3,000; a loss puts $2,000 in focus. XRP needs $1.25 to hold and a sustained close above $1.56 to open the path toward $2; $1 is the downside. Bitcoin rebound prospects depend on whether buyers defend key support levels, according to crypto analyst Ali Charts. The analyst named $81,000 for Bitcoin, $2,350 for Ethereum, and $1.25 for XRP as the levels to watch. Each asset has reached a technical test on its daily chart. Holding these zones could trigger recoveries across all three assets in the near term. A breakdown, however, would shift attention toward lower price targets instead.Bitcoin Rebound Depends on $81,000 SupportAli Charts shared the outlook in a thread on X on October 18. For Bitcoin, the analyst pointed to $81,000 as the key level. This price marks the lower boundary of its daily rising channel. The channel connects a series of higher lows and higher highs on the daily chart.2/5 For Bitcoin, the level is $81,000, the lower boundary of its daily rising channel. If buyers defend it, $BTC could rebound toward the channel’s mid-range at $84,000, then to its upper boundary at $86,500.A break below $81,000 would shift my focus to $76,000. pic.twitter.com/Ev21vQ1GLz— Ali Charts (@alicharts) October 18, 2026If buyers defend that support, BTC could rebound toward the channel’s mid-range at $84,000. The $84,000 mark sits near the midpoint of the channel. From there, the next target sits at the upper boundary near $86,500.However, a break below $81,000 would change the setup. In that case, the analyst would shift focus to $76,000 as the next level. The $76,000 level would then become the main area for buyers. The Bitcoin rebound case therefore rests on this single channel boundary.Ethereum Tests $2,350 SupportEthereum faces a similar test at $2,350. This level acts as the support line of a right-angled ascending broadening pattern. Such patterns form when price swings widen while support rises over time.A bounce from this zone could lift ETH toward $2,700. A stronger move could extend the rally to $3,000. The $3,000 target would require sustained momentum after the first move. Both targets depend on buyers holding the pattern’s lower boundary.On the other hand, a daily close below $2,350 would change the outlook. A close below that line would invalidate the support the pattern relies on. In that scenario, the analyst would watch $2,000 instead. Ethereum therefore needs to hold that line on a closing basis.XRP Watches $1.25 Inverse Head-and-ShouldersFor XRP, Ali Charts is watching $1.25. Holding this level could complete the right shoulder of a potential inverse head-and-shoulders pattern. The pattern appears on the 3-day chart. This formation often signals a potential trend reversal when the price breaks above its neckline.The rebound would still need confirmation, though. A sustained close above $1.56 could open the path toward $2. The $1.56 level acts as the resistance XRP must clear first. Such a move would confirm the setup on the higher timeframe.Failure to hold $1.25 would change the picture. In that event, $1 becomes the downside level to watch. That level would mark a drop of roughly 20% from the $1.25 support. All three setups, including the Bitcoin rebound case, depend on support holding in the coming sessions.The post Bitcoin, Ethereum, and XRP Reach Critical Support Zones: Here Are the Levels to Watch appeared first on Blockonomi.
