So basically, they just want to earn from their clients buying Bitcoin without actually holding any Bitcoin themselves.
Banks were afraid of bitcoin because it could "steal" their clients and therefore, they openly hated it, like Jamie Dimon. But as soon as these banks figured out how to make money using bitcoin, their rhetoric immediately changed.
And people are ready to blindly trust these greedy hypocrites.
Honestly, it might be better for clients to just buy directly from exchanges and learn how to secure their assets properly. Banks arent really that helpful when it comes to Bitcoin investing. All they do is act as a bridge for traceable transactions and once thats done, they collect their fees and call it a day.

Clients are too lazy to deal with all this. Therefore, it is easier for them to pay the commission and enjoy life, receiving dividends from these pseudo-investments in bitcoin. I am sure there will be many such people. Also, there is an element of trust and reliability that such banks instill in people. In fact, pseudo-reliability.
