differing base currencies for investments

[Varunram]

Some projects might want to raise money purely in crypto - xlm / btc only for examples. Such investments might not need KYC (#218) and can be invested in by multiple people. There is no risk involved since we don't hedge against USD, the project's base currency is in crypto, so there are no conversions involved. Exchange of assets on the secondary market would also be interesting since a crypto native project can be used to hedge against a USD native project (and the other way around).

An extension of this would be having partial goals in each currency - 2btc + 100000XLM funding goal for example should be achievable and investors who invest in that particular currency get assets that are native to that chain (eg. liquid assets for bitcoin and xlm assets for Stellar)
