I hope people think about this and then bitcoin is used mainly as a currency instead of an investment option. Then only it can live for forever.

Volatility is the only reason why it has not become popular as a currency. Only a limited people use it as a currency currently.

I panicked only once, when there was news that banks in my country will not work with exchanges. Now that matter is in court.

It does not make any sense to call bitcoins a  scam even after 8 years. So they have finally accepted that it has real value and use.  

Would you care to explain why we should invest in this project instead of other reliable options ? What unique features this coin got ?

Why are you showing so much impatience. Hold them for years to get decent returns, invest only in top 10 coins.

I will suggest you to split this in two parts and invest in ETH and BTC. Expect at least 4x in one year and 100x in next 10 years.

No one can tell which is best as different from one person to another. Some like to participate in campaigns giving alt coins while other want to choose those which are paying in bitcoins. 

No, they are going to ban it completely. They will have to first pass a bill for this in the parliament, it can take a month or more.
