I am still confused, whereas my friend's suggestion he said better buy some btc

Because it's very possible that the price of bitcoin will go higher after August 1. And if you will wait after August 1 the price can be higher already and you won't have any sense of buying on that stage because you'll regret that you never bought earlier. Good thing you have a friend that is suggesting you to buy more and it's like buy at your own risk.
It really depends on what you are comfortable, your economic means and the risk you are willing to take, if you prefer to play it safe then the best thing you can do is to hold and do not move your coins for some time until things settle and we get to know what is the outcome of all of this.
