Let's say you plan on holding 10 BTC, and hope it will be worth 1 million USD one day… time comes to sell/spend your BTC. You are now dealing with a wallet worth 1 million USD…isn't that a bit undesireable. Despite the "high" tx fee, wouldnt you be better off splitting your BTC up into smaller denominations, say .5 BTC in each, say paper wallet. This way you are only ever dealing with 50,000 USD at a time. Has anyone thought of this?
