It doesn't have to be all or nothing. The proper strategy would be to sell a percentage at $10.

In fact, if you started in 2011 with 1000 BTC and every year you sold 50% then today you'd have (by my rough calculations):

8 BTC (worth about $50k)

$160k USD

Of course it's not the millions you'd have if you just held each time, but for many that is a life changing amount of money and you would have obtained it in a responsible manner that doesn't just rely on the value of Bitcoin shooting to the moon.
