XRP Price Prediction: XRP Flips BNB To Third As Ripple Drops Quantum-Proof Roadmap

$XRP trades at $1.4293 on April 21, up 0.30%, flipping $BNB to third largest cryptocurrency by market cap at $87.5B as Ripple releases a four-phase quantum-resistance roadmap targeting full XRPL protection by 2028.

$XRP Daily Chart: Three EMAs Below Price For The First Time Since October

The descending channel from the August peak near $3.60 remains the long-term structure. Within it, the picture has shifted. The 20-day EMA at $1.3924, 50-day at $1.4119, and SAR at $1.3771 have all crossed below price and now sit as support. The 100-day at $1.5393 is the next resistance above, with the 200-day at $1.7857 and the channel boundary beyond that.

Price at $1.4293 sits between the 50-day and 100-day, above three EMAs for the first time since October. A daily close above $1.5393 clears the 100-day and puts the channel boundary at $1.60 to $1.65 in view. Losing the 50-day at $1.4119 on a daily close puts the 20-day at $1.3924 then the SAR at $1.3771 in play.

Key levels for April 22:

• SAR support: $1.3771
• 20-day EMA: $1.3924
• 50-day EMA: $1.4119
• 100-day EMA resistance: $1.5393
• 200-day EMA: $1.7857
• Channel upper boundary: $1.60 to $1.65

$XRP Flips $BNB, XRPL Volume Tops $1B, ETF Inflows Hit $1.2B In One Week

$XRP climbed 6% on the week to cross $87.5B in market cap, overtaking $BNB for third place behind Bitcoin and Ethereum. XRPL transaction volume topped $1B in the same period, confirming the price move has on-chain usage behind it. ETF inflows hit $1.2B alongside, putting $XRP’s institutional demand in the same conversation as Bitcoin’s ETF story from earlier this year.

Three catalysts in a single week, a market cap flip, a volume record, and $1.2B in ETF inflows, rarely land together. The case that $XRP’s recovery from the February low is demand-driven rather than speculative gets harder to dismiss.

Ripple’s Four-Phase Plan To Make XRPL Quantum-Resistant By 2028

Every time an XRPL account signs a transaction, its public key becomes visible on-chain. A quantum computer can reverse-engineer the private key from that exposure and drain the account. Long-held accounts with extended public key visibility carry the highest risk.

Phase 1 is the emergency response. If quantum computers arrive faster than expected, classical signatures stop being accepted and all funds must migrate to quantum-safe accounts. Zero-knowledge proofs let holders prove ownership and migrate without exposing the key.

Phase 2 is already running, with Ripple’s cryptography team assessing XRPL’s full quantum vulnerability alongside research firm Project Eleven, targeting H1 2026 completion.

Phase 3 in H2 2026 integrates quantum-resistant signatures on the developer test network without touching the live network.

Phase 4 by 2028 proposes a full network amendment for native post-quantum cryptography at scale. Google recently warned quantum computers could attack Bitcoin with less power than previously estimated, with analysts flagging 2029 as a potential Q-day. Ripple’s 2028 target lands one year ahead of that.

$XRP Price Prediction: April 22 Outlook

• Upside: The 50-day EMA at $1.4119 holds, daily close above the 100-day at $1.5393 clears the next layer, and the channel boundary at $1.60 to $1.65 becomes the target. ETF inflows above $1B per week and XRPL volume above $1B per day keep both the institutional and on-chain cases intact.
• Downside: The 50-day at $1.4119 breaks on a daily close, 20-day at $1.3924 is next, then the SAR at $1.3771. A close below the SAR puts the channel interior back in play and the February low at $1.15 in view.
