Not without trusting a third party that they're not going run off with your money. Also, coinjoins on BTC are craxy expensive because transaction fees are crazy high.

Luckily BCH has near-perfect coinjoin privacy with CashFusion. It is capable of running > 20 person coinjoin rounds with no change outputs and no trusted third party. And the transactions always cost a fraction of a penny cause BCH has reasonable sized blocks.

Its not really that hard. Just mix the coins somehow after purchase.
