A Bitcoin mixer (also called BTC tumbler or Bitcoin blender) is a privacy service that breaks the on-chain link between sender and receiver. BitStorm works by pooling your BTC with thousands of other users' coins, then sending different coins to your output address. This makes blockchain analysis unable to trace the origin of your funds. BitStorm uses CoinJoin technology at higher fee tiers for cryptographic unlinkability.
Our tumbler operates a strict no-logs policy. All transaction data, deposit addresses, and output addresses are automatically purged from our servers after 24 hours. We require no registration, no email, no KYC verification. The service is accessible via Tor for additional anonymity. Your Letter of Guarantee can also be auto-deleted
The minimum amount to mix on our Bitcoin Tumbler is 0.001 BTC. There is no maximum limit. For very large amounts, we use our own reserves of mixed Bitcoins. So you can mix any amount you need.
Procces takes 30–45 minutes from the moment you send Bitcoins. It depends of mempool fee and how miners pick up your deposit in a block. For faster transaction speed use "high priority" fees in your wallet.
Yes. Our tumbler supports up to 5 output addresses. You can paste up to 5 addresses separated-with-dashes. Example: address1-address2-address3... Splitting output across multiple wallets adds an additional layer of privacy by making it even harder to associate the mixed coins with a single recipient.
Every standard Bitcoin script type is accepted on input and output. P2PKH (Legacy, 1…), P2SH (3…), Bech32 SegWit (bc1q…), Taproot (bc1p…). The mixer routes the payout to whatever script type matches the receiving address you paste — you do not need to convert anything before depositing. Hardware wallets, mobile wallets, multisig coordinators and node-backed wallets all work; the mixer only sees a UTXO, never the wallet behind it.
Walk through three checks in order. (1) The deposit address on your order page must match the address in your wallet history exactly — Bitcoin transactions are irreversible, a single typo means the BTC is gone. (2) The deposit must be at least 0.001 BTC; below the floor and the mixer will not process it. (3) Your transaction must show up at the deposit address on mempool.space. If all three hold, the deposit is en-route and only needs 1–3 confirmations; otherwise contact support with your Order ID and the broadcast TXID.
Not from on-chain data alone. The payout is constructed from a disjoint UTXO set, so common-input-ownership and change-output heuristics terminate at the mixer boundary — chain-analysis tools cannot walk back from the receiving address to the original wallet. The protection is broken only by off-chain leaks you create yourself: redepositing mixed BTC into a KYC exchange (which then ties the new wallet to your KYC identity), reusing the receiving address for clearnet payments (donations, social-media tip jars, ad networks), or co-spending pre-mix and post-mix outputs in a single transaction. The mixer secures the chain. The user must keep their wallet hygiene.
CoinJoin is a Bitcoin privacy protocol invented by Gregory Maxwell. Multiple users combine their transactions into a single transaction, making it cryptographically impossible to determine which input corresponds to which output. Bitcoin-tumbler.com implements CoinJoin for a maximum privacy tier, providing the strongest mixing that even advanced tools like Chainalysis cannot reverse.
