I have the Minecraft java edition and want to play on Hive or Cubecraft (Bedrock edition). Is there a way I can play on Bedrock servers like the geyser server?
Geyser is actually also available for other devices besides Java Server. You can just install it as a proxy. Otherwise you can also get a Minecraft Bedrock license if you already have Minecraft Java. Just google it once
No, the Bedrock license was a time-limited offer and is no longer valid
You could have googled too
