Your feeling would be like if you lose your smartphone with all your contacts... sadness for a while...until you buy a new phone and ask to people you know to give you their numbers again.
I lost BTC0.05 earlier in a local basketball game and I feel like I lost BTC0.5. So I can't imagine what will be the feeling if I lose BTC10.
I lost 0.3 BTC in Clam and I feel like I lost my life.
