Just found this offering by Luzerner Kantonalbank. Not too bad actually, wdyt?
Handelsmarge pro Transaktion:
Storing: 0.6%pa
Sie können Kryptowährungen gegen CHF oder nach Bedarf gegen sämtliche verfügbaren Währungen handeln
Übertragen Sie Ihre Kryptowährungen einfach und sicher von und zur LUKB.
Not sure if srs. Let me give you an example with Relai:
Up to CHF 100, as monthly standing order: 0%
Up to CHF 100’000: 0.9%
Over CHF 100’000: 0.8%
Over CHF 250’000: 0.7%
Over CHF 500’000: 0.6%
…
Over CHF 50 Mio.: 0.2%
Storing: 0% p.a.
And on actual exchanges, you pay a third of even that. With huge liquidity, most coins that have any relevance at all, and many, many features (send/receive, stake, margin, etc.).
Why can’t Swiss banks offer at least somewhat competitive products?
Please always remember
“Not your keys, not your coins”
I somehow don’t think that people who ponder going through a bank to hold crypto really care at all about the difference between direct ownership of a crypto asset and the handling of fiat currencies by governments and the heavily regulated banks.
Meh, we trust brokers for other assets as well. If a crypto broker was a single point of failure for a large part of my assets that would change the picture. 5% does not. Transaction costs, chance of messing up, and general maintenance when holding multiple crypto assets seems disproportionate.
Well there is clearly a big difference of brokers vs. crypto exchanges. One of them is that (conventional) brokers are far more regulated & conservative than crypto exchanges.
Like I have never even heard of the CEO of IBKR, while many crypto exchanges have, lets say, ‘more interesting’ CEOs 
But yeah, LUKB would not be one of these ‘interesting’ cases & one of the reasons would be that crypto is not their core business (yet? 
).
