I just stop looking at bitcoin price. It hurts me actually, that's why I took this decision. I am holding few of BTC and I will not look at my wallets too for 2 months. I hope after 2 months when I will go to see bitcoin price, maybe I will scream happily. What about you guys? 
To those who plan or already investing in long term I suggest to stop watching bitcoin price daily so your not influence to sell your bitcoin once the bitcoin price drops.
