How I Got Tricked by a Replay Attack—And Lost My BCH

After 10 long years, I finally cracked the code—I remembered my Bitcoin wallet password! A rush of excitement hit me. Not only did I regain access to my BTC, but I also discovered that I owned its forked versions like Bitcoin Cash (BCH) and eCash (XEC). Jackpot!

With dreams of consolidating my crypto into a multi-platform wallet, I set things in motion. My plan? Transfer my XEC from Electrum ABC to Binance. Simple enough, right?

Wrong. Very wrong.

The Vanishing Act

Minutes after my XEC transaction was confirmed, I casually checked my Electron Cash wallet—only to find my BCH completely gone. Vanished. Poof! 333.9 BCH—wiped out in seconds.

What just happened?!

The Hidden Danger of Forked Coins

Turns out, I had just fallen victim to a replay attack. Here’s how this sneaky exploit works:

1️⃣ When a blockchain forks (e.g., Bitcoin → Bitcoin Cash), both chains share the same history up to the split.

2️⃣ Unless proper replay protection is in place, transactions on one chain can be “replayed” on the other.

3️⃣ Since my XEC wallet address was derived from the same private key as my BCH address, my transaction unknowingly went through on both chains—draining my BCH in the process.

The worst part? The recipient address wasn’t controlled by Binance, meaning my BCH was gone forever. 💔

Lessons Learned

Always use a replay-protected wallet when dealing with forked coins.

Split your coins properly before making transactions.

Never assume different blockchains will treat transactions separately.

Thankfully, I lost only a small amount—but it could have been a nightmare. My first-ever crypto, gone in a flash. The emotional loss? Priceless.

If you’re deep into crypto security, tell me—is there any way to reverse this? (Though I highly doubt it.)

Stay safe, stackers. The crypto jungle is wilder than ever. 🚀
