Feature requests: Exchangerate Provider for crypto currencies

[pat-s]

Is your feature request related to a problem? Please describe.

Better support for crypto currencies, especially with respect to adding "staking" returns.

When booking these returns as dividends, one always needs to add a value in EUR/USD. In addition one needs to add a "buy" to afterwards to reflect this reward in the portfolio again. However, doing so blurs the "buy" statistics as these events are not really "buy" events.

Having official support for such currencies in the "currency" setting could make it possible to book the rewards in the native currency directly and reduce the two-step approach from above. This was also mentioned and discussed in this forum post.

Describe the solution you'd like

• Official support for crypto currencies in the "currencies" setting (happy to help adding currencies)
• An Exchange Rate provider for crypto currencies which is able to convert between fiat and crypto. (currently there is only "FixedExchangeRateProvider" and "ECBExchangeRateProvider"). The provider could either be one of the large exchanges or an independent platform (e.g. coinmarketcap)

Describe alternatives you've considered

The two-step workaround from above which is not a long-term solution and has negative consequences on the "buy" statistics.

Additional context

"Staking" rewards are dividends in the native currency of a coin which can be either auto-compounded or being sent to a wallet.
