After August... Will Bitcoin still stay Safe Store value ????

So Recently it started that Bitcoin was widely accepted and few countries considered it an secondary currency and in few you can open a bank account where you can store Bitcoin in bank account....(Not sure about the interest rate you would get for long term Deposit.. I am sure it would be less than actual BTC trading)... well.. So In short BTC has established itself as Crypto King and almost replaced the Fiat currency for the National... Almost.( Still waiting for my Lambo... )

Investing in BTC has more growth potential and better returns than in Gold.....

I was totally sold by this BTC Story and thought the party just started and so the BTC story was going great but then the BTC community decides to Fork BTC .. why ?? Why ??? Why ????

Come August BTC would be split in BTU & BTC similar to ETH & ETH Classic... So which Bitcoin(BTC / BTU) will reach safe store or ETH will Kick Bitcoin from the King Title ????
