Pros and cons

Pros

  • Wide listing for a retail exchange at from 350 coins
  • Taker fees of 0.1% to 0.8% sit under the site median of 0.2%
  • Staking is offered alongside custodial custody

Cons

  • Support runs on help centre only, so there is no direct contact route when an account issue is urgent
  • Custody is custodial, so the platform holds the keys rather than you
  • Maker and taker fees share the same 0.1% to 0.8% range, so there is no discount for adding liquidity

Safety and regulation

Kvarn X FI is supervised by FIN FSA and Finanssivalvonta (FIN FSA), and the authorisation is recorded as MiCA CASP 9845009F15A5B9FD7F45. That registration is the practical difference here: around 78.8% of the exchanges in this comparison run as custodial platforms, but only a minority of those can point to a named MiCA licence. Funds sit with the operator, which is the trade-off for anyone who would rather hold keys themselves.

Who runs it

The operator is Kvarn Capital Oy, headquartered in Finland, and registered with the Finnish authority as MiCA CASP 9845009F15A5B9FD7F45. Support is limited to a help centre, so most questions are answered by articles rather than by a person. About 158 of the 298 venues in this ranking hold a licence, which puts Kvarn X FI in the smaller regulated group.

Frequently asked questions

What does it cost to trade on Kvarn X FI?+

Trading costs 0.1% to 0.8% as a taker and 0.1% to 0.8% as a maker. The maker rate matches the taker rate, so there is no rebate for posting liquidity. That sits against a site median taker fee of 0.2%, and inside the range most of the 298 exchanges in this ranking fall into.

Is Kvarn X FI regulated?+

Yes. It is listed with FIN FSA and Finanssivalvonta (FIN FSA) and its MiCA authorisation appears as MiCA CASP 9845009F15A5B9FD7F45. That places it among the 355 licensed operators on the site, rather than the larger group of exchanges that operate without a named authorisation.

Who holds my crypto?+

The exchange does. Custody is custodial, meaning balances sit with the platform rather than in a wallet you control. Roughly 51% of custodial products on the site work this way, and about 13.1% of ranked exchanges let you hold the keys yourself instead.

How many coins can I trade?+

The listing covers from 350 coins, which puts Kvarn X FI well above the 74.5 median coin count for ranked exchanges. Breadth is the main draw if you want a long tail of tokens in one account rather than spreading holdings across venues.

Does Kvarn X FI offer staking?+

Yes, staking is one of the features offered on top of custodial custody. About 10.6% of the products on the site include staking, so it is a common enough addition, but the rate itself is not published, so the return has to be checked on the account before you commit funds.

How do I get help if something goes wrong?+

Support comes through a help centre. There is no chat, email or phone route listed, which is lighter than the 34.9% share of products that offer live chat. If your issue needs a person rather than an article, that is the practical drawback to plan around.

What kind of exchange is it?+

It is a centralised exchange, a custodial setup where the platform holds assets and matches orders. About 91.2% of the products on the site are centralised, so this is the mainstream model rather than a decentralised alternative.
