Our verdict
Braiins runs Slush Pool, a Bitcoin mining pool rather than a retail earn account, so it suits miners and BTC holders who want flexible payouts. Custody is custodial, the pool has run since 2011, and help runs on help centre alone, with the operator based in Czechia.

Pros and cons
Pros
- Payouts are Flexible payouts, so miners can move earned rewards on their own schedule.
- A single-asset focus on BTC keeps pool maths and payouts easy to follow.
- A long record, with the operation dating back to 2011.
- Backed by Braiins Systems s.r.o., headquartered in Czechia.
Cons
- Custody is custodial, so your balance depends on the pool operator rather than on your own keys.
- Help runs on help centre only, with no live or phone channel listed.
- Earning is limited to BTC alone, next to TAO, ADA and TIA at bunq Crypto Spain.
Who it suits
- Miners with BTC hash power who want flexible payouts rather than a locked balance.
- BTC holders who accept custodial and treat this as a mining pool, not a savings account.
- Readers judging a pool on track record and payout terms rather than on a listed earn rate.
Who should look elsewhere

Frequently asked questions
Is Slush Pool a savings account for crypto?+
Not quite. Slush Pool is Braiins' Bitcoin mining pool, so rewards come from mining rather than from lending out a balance you deposit. Assets listed are BTC only, and custody is custodial, which is a different arrangement from a retail earn product.
How are mining rewards paid out?+
Payouts are Flexible payouts, so miners can trigger withdrawals instead of waiting on a fixed schedule that holds the balance. That suits anyone who wants to move part of the earnings as they accrue, and it keeps the product away from term-deposit waiting periods.
Which assets can I earn on here?+
Only BTC is supported. Compare that with BTC, ETH and B2M at Bit2Me and TAO, ADA and TIA at bunq Crypto Spain if you would rather spread an earn balance across several coins.
Who holds the coins I mine?+
Custody is custodial, so the pool operator looks after the balance rather than you holding the keys. The legal entity behind the pool is Braiins Systems s.r.o., based in Czechia. Readers who want their own keys should treat this as a different kind of product.
How long has the pool been running?+
The operation dates back to 2011 under the Braiins name, and the entity behind it is Braiins Systems s.r.o. in Czechia. Track record matters in mining, where uptime and consistent payouts drive income far more than a headline figure.
How do I get help if something goes wrong?+
Support runs through help centre only, with no live or phone channel listed. For a mining pool that means answers mostly come from written articles, so account-specific problems can take longer to resolve than with a staffed desk.
How does the return compare with other earn products?+
Slush Pool is a mining pool, so it carries no listed savings rate to put next to the earn products here, where the median yield is 7%. Read any headline rate on this site as belonging to that earn product, not to Slush Pool.
