Crypto assets can be purchased with settled cash only.
Please note that while crypto buys and sells settle immediately in the account (i.e. no settling period), securities transactions take one business day (T+1) to settle, so cash resulting from a security sell today will be reflected in the Non-Marginable Buying Power (i.e. crypto buying power) after one business day.
If you do see the amount reflected in your Non-Marginable Buying Power attribute and still getting the error, please donât hesitate to reach out to [email protected].
