Hello Aternos Team,
could the mod "Bitcoin" be added to your mod list?
Link: https://www.curseforge.com/minecraft/mc-mods/bitcoin
Bitcoin is a Thermal Expansion addon mod, where you can go mining for Bitcoin ore, process it and get Bitcoins, which give you RF when put into a special dynamo. The Bitcoins have an ever changing value of RF it gives, and it gives the RF amount at the time when it was put into the numismatic dynamo.
Really hope to see this mod on 
Have a good day,
vonotige.
