Do you think we should change our attitude towards bitcoin ? Don't you think we should use BTC as a medium instead of capital gain.

[Is it a good decision or bad?]

Tax law is dependent on your country and locality. Recently in the United States, the IRS has declared that Bitcoin is to be treated as property, not currency, for tax purposes. All income in the US is taxed, regardless of what form it takes. If you’re paid in bitcoins, you’re supposed to pay taxes on your earnings at the BTC/USD exchange rate when you receive payment.

Is it a good decision or bad?

I think the only bitcoin can make this cryptocurrency market stable. BTC was doing monopoly business over last few years. It's time to do some competition with other good currency. Am I right or wrong?

Altcoins can differ from Bitcoin in a range of ways. Some have a different economic model or a different coin-distribution method, like altcoins that were given away to all citizens of a country. Others employ different proof-of-work mining algorithms, perhaps to resist specialized mining hardware — or maybe they don’t even rely on proof of work at all. Several altcoins offer a more versatile programming language to build applications on top of, while yet others offer more privacy compared to Bitcoin. And there are also altcoins that serve very specific, non-monetary use cases, like domain name registry or data storage pointers.

I did some research for last few months regarding cryptocurrency. I got some crucial questions in my mind. One of the questions is: Will other coins go to near to the bitcoin value or bitcoin will go up again?
