Onramp Finance (exchange and brokerage) and Coldcard (hardware) serve different corners of the Bitcoin ecosystem, but the question that matters most is the same: who controls the keys? In our scoring model, Onramp Finance holds a commanding lead at 89/100 (A) compared to Coldcard at 58/100 (C). That 31-point gap reflects real, measurable differences in how each platform handles custody, fees, and transparency.

Coldcard charges ~$150 one-time compared to 0.59% one-time at Onramp Finance. Over a multi-year holding period, fee differences compound — a point worth considering for long-term accumulators.
