As a crypto-financial service provider, it is not Bitcoin Suisse’s main focus to optimize fiat holdings. Maintaining fiat holdings entails operational costs for Bitcoin Suisse. To prevent the need for future fees on fiat holdings for clients, we suggest that clients with substantial fiat holdings held at Bitcoin Suisse for an extended duration consider withdrawing these funds or buy a suitable stablecoin. Holding USDC and/or EURC at Bitcoin Suisse is advantageous because it is exempt from the crypto custody fee.
