Using binance without 2fa
While the withdrawal limit on the Binance exchange even for unverified accounts is enough for most people, there are some other reasons to verify an account. The first is that two-factor authentication increases account security. The second is that Binance may unexpectedly decide to require you to verify your account before you can withdraw and money.
Withdrawals should generally work on unverified accounts, but Binance may suddenly require verification. Therefore, it is probably best to go through the process of verification before you deposit any coins.
Many people have stories about depositing funds to Binance and then being unable to withdraw them.
