Under the supplied tracing rules, Evan’s $50,000 offer is far too low. The calculations and discovery position are below.

## 1. Commingled 12 BTC after marriage

Evan commingled:

- 8 BTC separate/premarital
- 4 BTC marital

Because the BTC are indistinguishable:

- Separate fraction: **8/12 = 2/3**
- Marital fraction: **4/12 = 1/3**

## 2. Sale of 3 BTC

The 3 BTC sale is drawn proportionally from the mixed pool:

- Separate: 3 × 2/3 = **2 BTC**
- Marital: 3 × 1/3 = **1 BTC**

The sale proceeds went to the joint account and were spent on ordinary household expenses. Under the governing rules, those proceeds are not reimbursed to either spouse. They are not added back into the divisible estate.

Remaining 9 BTC:

- Separate: **6 BTC**
- Marital: **3 BTC**

So the remaining 9 BTC remain **2/3 separate and 1/3 marital**.

## 3. Exchange of 6 BTC for 90 ETH

The 6 BTC surrendered had the same proportional character:

- Separate: 6 × 2/3 = **4 BTC**
- Marital: 6 × 1/3 = **2 BTC**

Under the exchange rule, the 90 ETH takes the same character:

- **60 ETH separate**
- **30 ETH marital**

The remaining 3 BTC are:

- **2 BTC separate**
- **1 BTC marital**

The later transfer of 30 ETH to the cold wallet does not change character.

## 4. Valuation of known traced crypto

Using the valuation-date prices:

- BTC = $50,000 each
- ETH = $3,000 each

### 3 BTC

- Separate: 2 BTC = $100,000
- Marital: 1 BTC = $50,000
- Total: $150,000

### 90 ETH

- Separate: 60 ETH = $180,000
- Marital: 30 ETH = $90,000
- Total: $270,000

### Known traced crypto totals

- Separate: **$280,000**
- Marital: **$140,000**
- Total: **$420,000**

Mira’s one-half share of known marital crypto:

- **$140,000 ÷ 2 = $70,000**

So even before the second wallet, Evan’s $50,000 settlement offer is below Mira’s known marital share.

## 5. Second 40 ETH wallet

The 40 ETH is worth:

- 40 × $3,000 = **$120,000**

It arrived during marriage in an undisclosed wallet. Evan claims it was a gift from his brother, but he has produced no exchange records, no donor wallet records, no gift documentation, and no brother testimony.

Under the rules, property in an undisclosed wallet during marriage is presumptively marital unless the holder traces a separate source. Evan has not done so.

**Provisional classification: marital.**

If the 40 ETH is marital:

- Mira’s ordinary one-half share: **$60,000**
- If Evan intentionally concealed it in his sworn disclosure, 20% surcharge:  
  **20% × $120,000 = $24,000**
- Mira’s total recovery from the second wallet with surcharge:  
  **$60,000 + $24,000 = $84,000**

Including the known traced crypto and the second wallet:

- Total marital crypto: $140,000 + $120,000 = **$260,000**
- Mira’s ordinary half: **$130,000**
- Plus concealment surcharge: **$24,000**
- Total potential recovery: **$154,000**

This assumes the court finds intentional concealment. The sworn omission and discovery only after the tax request support that finding, but the court must make it.

## 6. Evidence still needed

Before settlement, Mira should seek targeted forensic discovery for:

### Exchange records

- Records of the premarital 8 BTC ownership and transfer into the wallet.
- Records of the joint-account purchase of 4 BTC during marriage.
- Records of the sale of 3 BTC, including the exchange statement and destination of proceeds.
- Records of the exchange of 6 BTC for 90 ETH, including trade confirmations, fees, and wallet addresses.

### Wallet records

- All wallet addresses controlled by Evan, including:
  - the combined BTC wallet
  - the original ETH wallet
  - the cold wallet
  - the second undisclosed wallet
- Transaction hashes for:
  - the 8 BTC deposit
  - the 4 BTC purchase deposit
  - the 3 BTC sale withdrawal
  - the 6 BTC exchange withdrawal
  - the 90 ETH receipt
  - the 30 ETH cold-wallet transfer
  - the 40 ETH receipt into the second wallet
- A forensic blockchain tracing report connecting each transfer.

### Donor/gift records for the 40 ETH

- Brother’s wallet and exchange records.
- Proof of the brother’s ownership of the sending address.
- Any gift message, email, text, or document showing donative intent.
- Brother’s testimony or affidavit.
- Tax records showing the source and transfer of the 40 ETH.

## Recommendation

Do **not** accept the $50,000 settlement.

Mira’s known marital half alone is $70,000, and the second wallet is likely marital, adding another $60,000 ordinary share plus a possible $24,000 concealment surcharge. The missing evidence is central, and Evan cannot avoid tracing by saying wallet transfers are “too technical.”

The correct step is to seek a targeted forensic order compelling disclosure of the exchange, wallet, and donor records before any final division or settlement.
