With Revbit, you can zero in on what altcoin to buy right now and turn market hype into serious gains. For altcoins like XRP or Stellar, Revbit also guides you on what is a crypto memo (like the XRP destination tag) to ensure your deposits land smoothly.
Crypto Quick Pit Stop
Since we’re talking transfers, let’s clear up what is a crypto memo for altcoin traders. For tokens like XRP or Stellar, exchanges use a memo (or destination tag) to route deposits to your account on a shared wallet. What is memo in crypto transfer? It’s a unique code you must include to avoid losing funds—like the XRP memo tag for deposits to Revbit. Skipping it could delay or derail your trades.
Revbit’s deposit page makes this easy, clearly showing the memo tag crypto field when needed. A crypto investment memo, by contrast, is a different beast—a report for analyzing a project’s long-term potential, not a transaction tag.
