jm memoMPSA: be careful if you have wallets with a lot of bitcoin. quantum computing technology is about to be able to allow potentially bad actors to crack asymmetric encryption and transfer your coins out. Security through obscurity - I recommend moving your coins into multiple wallet addresses so that you aren't the biggest low hanging fruit. They wouldn't go after Satoshi's coins because everyone would notice.
