Q:should be possible exchange gold in silver (and silver in gold) from some npc or only from players ??? And from players in which ways?
Albion Online Gold can be traded between players or put on the Marketplace for sale for silver, in-game currency. There will also be premium account status, which can be bought in-game with gold. This gives slight boosts to silver gain and the destiny board, but won't give combat bonuses
but I couldn't find it right away. About what you can spend gold/Albion Online silver on:
|Guild Territory costs (Purchase, Rent, Attacks)||Silver, Gold|
|Personal Plot costs (Purchase, Rent)||Silver, Gold|
|Refining Resources||Silver, Gold|
|Crafting Items / Repairing Items||Silver, Gold|
|Constructing Buildings / Repairing Buildings||Silver, Gold|
