It is extremely rare I will ever shill for any company, but today I'm shilling for two bitcoin companies (never worked for either of them, but Trezor and Swan have done a good thing here)

Here is their DCA partnership / innovation:

(I wasn't paid to post this, but I saw it emerge somewhere on LinkedIn and was glad to see this sort of thing happening.)

Edit: The original post I saw on LI mentioned some Trezor and Swan collab / partnership, but apparently the DCA arrangement using Trezor includes more companies in total, which you can see from the page above, which I think are Invity, Swan, and BTC Direct in total.
