The Hedged Bitcoin service can be applied to funds deposited in fiat currencies or Bitcoin. The fiat currencies supported are USD, EUR, and GBP.
Please note that for fiat deposits in EUR and GBP, a conversion fee is applied based upon the Uphold Platform conversion costs. We do this because the Hedged Bitcoin dynamic portfolio is always composed of USD and Bitcoin, since that pair has the most liquidity in the market.
In addition, keep in mind that the Uphold Platform supports 33 other fiat and crypto currencies, all of which can be converted to USD or Bitcoin prior to activating the Hedged Bitcoin service.
