What does the 30-day limit at Bittr mean?

With Bittr, you can buy up to 999 CHF (or EUR equivalent) within a rolling 30-day window without verification via a bank transfer.

The calculation is always “today minus 30 days”, not the calendar month. If the limit is exceeded once (even if the purchase is then cancelled because no verification is desired), Bittr can only be used in the future after joining the Bittr Whales program. What counts is the time of the incoming payment at Bittr.

Regulatory basis

The basis for this limit comes from Swiss anti-money-laundering regulation: the Swiss Anti-Money Laundering Act (AMLA / GwG) generally requires a financial intermediary to identify customers as soon as a permanent business relationship is established. For so-called cash transactions without an existing business relationship, this obligation only applies from a “significant” amount, or if multiple transactions appear to be connected and together reach a relevant threshold.

FINMA specifies these requirements in the FINMA Anti-Money Laundering Ordinance (AMLO-FINMA / GwV-FINMA). For transactions involving virtual currencies, Art. 51a states that identification is required from 1,000 CHF, even if the amount is made up of several connected transactions. In practice, this threshold is assessed over a rolling period: what matters is whether multiple transactions are considered connected and, within 30 days, exceed the threshold in total. The limit is often confused with a “monthly limit”, but in practice it is calculated per 30 days.

Rolling 30 days vs. calendar month

A rolling 30-day limit recalculates, for each new transfer, the total of the last 30 days backwards from the purchase date. A calendar-month limit would only count from the 1st until the end of the month.

Three examples:

  • Alice buys 800 CHF on 15/01 + 500 CHF on 10/02 → That adds up to 1,300 CHF within 30 days, so she exceeds the limit even though she buys in two different months.
  • Bob buys 999 CHF on 15/01 + 999 CHF on 15/02 → He buys less than 999 CHF within 30 days and does not exceed the limit.
  • Carol sets up a monthly transfer at the start of the month: she buys 600 CHF on 01/02 and 600 CHF again on 01/03 → These two purchases are only 28 days apart. That adds up to 1,200 CHF within 30 days, so she exceeds the limit.

🚨 Although Carol buys monthly, she exceeds the 30-day limit because February is shorter.

FAQ

  • Is the limit per person or per bank account / email address / bitcoin address?

→ The limit applies per person, even if different bank accounts, email addresses or bitcoin addresses are used.

  • Can I run a monthly DCA plan with a standing order?

→ Yes, in principle. But it’s important to remember: the limit is rolling over 30 days, not per calendar month. In February/March, it can happen that a transfer on March 1st is still within the last 30 days since February 1st. In that case, the limit can be exceeded.

  • How do I know when the limit resets?

→ In the Bittr Dashboard you can see an overview of your purchases from the last 30 days and when your 30-day rolling would be reset. If you want to check specific gaps, you can also use a tool like “Time and Date Duration”.

  • If I transfer euros, is the limit 999 €?

→ No. The limit is 999CHF, not €999. For EUR transfers, the relevant value is the CHF equivalent at the exchange rate at the time of that transfer. Since the exchange rate fluctuates, a fixed euro amount may convert to more than 999 CHF at another point in time.
