01 · Purpose

The problem

Small-denomination foreign currency is often left unused because conventional exchange channels reject or under-serve it.

02 · Experience

How it works

The business concept aggregates unwanted currency, converts or resells it through an exchange model and presents the opportunity through an investor site.

What this record is grounded in

  • GitHub repository: simonmowatt1-sudo/coin-stash-solver
