I saw the latest release from Semler too. They now want to ditch their original business and just do the Saylor playbook.

I agree that it is odd that these companies don't feel the need to do anything with Bitcoin except fiat leverage it. Soon I think this won't be easily possible but even if they want to be a Bitcoin bank (oxymoron), you would think developing customer wallets, fiat integration systems for retail or lightning tech/nodes and lightning wallets.

Also showing proof of reserves etc..

These could be the next big rug, they are at least contenders imo.
