Bitcoin transactions are categorized by priority, normal, and low, you probably picked the low and used a small amount of fee to move your bitcoin, the last time I did that it took over a week plus before I could the bitcoin got to the destination and bitcoin was trading at $14k+ during that time, now it has risen up to $40k+ who knows how long its going to take , since you have already sent out the bitcoin, you can try using a bitcoin transaction accelerator, I don't know but it helps out a little.
