Is it worth selling all DOT for BDOT?

Currently 1 BDOT equals to 0.61 DOT. My understanding is that all BDOT will be automatically converted to DOT on 24 October 2023 at a 1:1 ratio.

Unless I am wrong (math is not my thing), if I exchange my DOT now, I will get +39% by that date, which is much higher than any staking APY.

Yes, I know that “not your keys - not your coins”, I take the risk. Other than this, is there anything else I shall consider? Do I miss something?

Thank you in advance.

UPD. Sorry I think I messed up with the math. 1 DOT is 1.637 BDOT, so it shall be roughly +63% in the end (unless I’ve messed up again :) )
