As described in the White Paper, BitEsprit sound to be the allrounder when it comes in term to exchanges.
You can trade a wide variety of altcoins against fiat. I don't even know one exchange, where this is possible.
And additonaly it's possible to follow other cryptotrades and make exactly the same trades.
BitEsprit is fully combatible to the ISO 27001 and PCI DSS standards, so there is a lot of security for the non-tec people out there.
