I think that he had over reacted in the matter of storing bitcoins.Its always advisable not to store bitcoins in any of the exchanges.Instead,he could have used  hardware wallet like ledger nano S or trezor for storing his bitcoins safely.

If any one knows that bitcoin has been stored in micro chips under the skin,then his life might be at serious risk as the bitcoin stealers would be willing to do any thing for obtaining bitcoins and and they would even cross any limits.
