People that have locked up BTS for bitAssets means they have bitAssets right? Nobody prevents them selling their bitAssets for bts and staking them to BEOS... Even if they must at some point protect their margin position they can freely sent back the staked bts on BEOS... It is not that they are locked for all 89 days ! You can move your bts back and forth...

PS I can only assume there is a misunderstanding on how the raindrop works.
