Bitwage actually lets you take as much % as you want as Bitcoin, and I know now also there are some solutions like BitPanda (I'm not 100% sure how it works so I could be wrong) that let you also set your "savings" automatically converting either a set amount or a set percentage of your balance in fiat at a set time. Sort of like enforced savings systems that I manually do myself anyway (except the other way round, converting a forced amount of btc into fiat!).
But both still mean you actually lose money (via exchange rate and commission) which is why there's still poor uptake IMO. Good luck and let us know how it goes.
Appreciate the insight, feedback!
FYI, in our first week live, we've onboarded 4 companies and have facilitated ~$200 in Bitcoin purchases and distributions. Not lambo standards at the moment, but we hope to keep building up from this
