A buyer of my bitcoin (over $1000 worth) claims to be limited to sending only $1000 a day. He’s sent the $1000 and says he will send the rest tomorrow. Is there any reason to be cautious of this trade or is it completely legitimate?
No need to be cautious any more than normal. Some users have limits on trades that prevent full payment being sent in one transaction.
The good news is that Zelle payment window is 4 days so ample time for the buyer to send payment in full even if broken down into more than one transaction.
This is common with Zelle and also Strike. They both like putting payment limits on their customers.
