Good afternoon all. I run a small online shop selling 3D printed parts, and cash flow is all over the place. Some months I need 3-5k fast to buy filament and maybe a second printer before a big order, then a few weeks later the money is back. A regular business loan feels like overkill for such short gaps. Part of my savings sits in crypto, mostly ETH. Is there something like a revolving credit line where crypto is the collateral and you only pay when you actually use it?
