since around august this year, bittrex requires every new user to complete the basic verification. the account without passing verification is pretty much useless since the withdrawal limit is very low
Nope, the withdrawal limit isn't low, it's zero, nothing, nada.
Without verification you can't withdraw a single penny.
No verification = lost money.
It's only happens if you have created the account on Aug 1 or after that. You can read on their announcement about daily limit
Please check below to see what limit your account falls under.
Unverified Accounts created before 08/01/17: 0.025 BTC (or equivalent) per day
Unverified Accounts created on or after 08/01/17: 0 BTC (or equivalent) per day
Basic Accounts: 3 BTC (or equivalent) per day with two-factor enabled.
Enhanced Accounts: 100 (or equivalent) BTC per day with two-factor enabled
A friend I advised to get a Bittrex account did indeed sign up after Aug 1, but wasn't make aware that they wouldn't be able to withdraw anything without verification when they signed up.
This is bullshit.
