Don't get me wrong, I still check the price every 30 seconds, but I don't care anymore if it goes up or down.
If up, I hodl.
If down, I buy more.
Doesn't matter to me.
I'm a millionaire in 2017 anyways.
This is why it's far less stressful to be a holder/hoarder than a trader/gambler.
Not caring is a difficult thing to do, but judging by people's experiences from years ago it's quite a healthy attitude.
