Our verdict on each
KakaoBank
KakaoBank suits Korean residents, businesses and teens who want a fee-free everyday account run from an app, with a currency conversion fee of 0% and a variable rate of 0.1%. The 2016 bank is licensed by the Financial Services Commission (Korea), so money sits with a regulated bank rather than an e-money firm.
SoFi
SoFi suits US savers who want an online savings balance held beside their checking account, with deposits covered by FDIC up to USD 250,000 and a variable interest rate. Because it is an online-only direct bank, the savings balance is managed from your own screen rather than a branch counter.

Questions about each
KakaoBank
Is there a monthly fee for a KakaoBank account?+
There is no monthly charge on the account, which ranks joint top of 500 brands on that measure. Transfers are also free: interbank and automatic transfer fees are waived, together with deposit, transfer and withdrawal fees at all-bank and convenience-store ATMs. The balance earns a variable 0.1%, settled monthly and paid the following day.
What interest does the account pay and is it fixed?+
The rate is variable at 0.1%, and it moves rather than being locked in. That is well under the 3% median across the site, and there is no notice period to serve and no cap on the balance, so money can be taken out whenever. It is a spending and payment account rather than a home for savings.
SoFi
How much does SoFi Savings cost to hold?+
Nothing is charged to keep the balance open. The monthly fee is $0, and the account model is no monthly fee. Money only becomes costly when you move it in certain ways, such as sending a wire rather than making a standard transfer.
Is my money safe with SoFi?+
It sits with a bank, and deposits are covered by FDIC up to USD 250,000, so the balance is protected up to that limit. The bank is listed as FDIC cert 26881, a certificate you can check against the insurer's register.
