Every time I try to move money between my bank and crypto I feel like a criminal even though I've done nothing wrong

My bank has flagged two of my transfers to a crypto exchange in the last three months. First time they put the money on hold for 48 hours. Second time someone from their fraud team called me to ask what I was buying and why. I answered everything honestly and they released the funds but the whole interaction felt accusatory. I'm not doing anything illegal, I'm just buying some ETH. Has anyone found a way to make this less terrible
