i think if big brand like amazon or ebay will take initiative to accept bitcoin as a payment than revolution will come in retail market. many of retail store will come in and start accept bitcoin as a payment.

Yes obvious price matter,
There are factor which attracts the investors one of factor is price of the particular.
For eg. when bitcoin was made price was about 0.004 USd/ btc, few of the people were interested to invested at that time, but after some time bitcoin price increased
than  investors shown interest. Yes price matter. 

yes we need both,
reasons :
1. around world there are countries who does not have internet access so how they can use bitcoin instead of fiat.
2. Blockchain technology is far better and secure than traditional way of transactions thats crypto is also has potential to change the world.

When i have gotten payment every week from campaigns than i let people know that i earned 30 bucks without doing much efforts with proof of earning.

If this is happened than where the govt earn money, you know most of govt income comes from taxes.
Taxless condition leads to stop development processes.

I am using zebpay which is best in india right now,
Just send amount of bitcoin to zebpay account address than simply convert it into fiat currency and withdraw it to bank directly. Simple process.

Bitcoin can be used as currency as well as asset also.
Some countries are legalize bitcoin and most of shops accept bitcoin as payment that point of view bitcoin is currency.
but if bitcoin is only used for trading purpose than it can treated as asset.

Yes I am true believer in bitcoins because bitcoin is really help me to survive for eg. Most of the expenses like Internet bill, electricity bill and many expenses have been paid by bitcoin earnings.

There is nothing to do with these kinds of people, Let them do whatever they want to, we can't actually force someone to use bitcoin or like bitcoins.

Worst decision that i ever made  i cash out most of bitcoin before 1 AUG hard fork but bitcoin value went high after hard fork.

Whenever we want to expertise in something than we have to go deeply to that particular thing and keep updated news, articles and joining the discussions. I think on bitcointalk we can gain lots of knowledge about bitcoin.

Before comes on weakness' of bitcoin we got to know everything has two aspect positive and negative.
Bitcoin has positive and negative also.
Here we just talk about negative

1. Yes i agree transaction can't be reversed.
2.  There is no Third party involvement like in banks we have policy and Central bank monetary.
3.  Bitcoin anonymous can be used for funding terrorism.
4.  One country behaviour can make effect on whole world bitcoin price eg. China banned exchanges and bitcoin    price    had fallen

Most comparative altcoins' to bitcoin right now is ETH and Zcash if am i not wrong,
But to cross the btc price, They have to more popular and Increase their working capital.
There is no effect on btc if altcoins its value over btc.

We can earn some bitcoin in signature campaigns', That's easy way to earn some amount of bitcoins but you should invest your value time in write good posts on bitcointalk.
You can also try free legit faucets but they are not such profitable.

Bitcoin vs ETH such a burning topic,
If we compare their value than one thing come in mind when the btc price rise than eth also rise. Why ETH is rising and falling with bitcoin ?
Most of the ICO token can we transferable with ETH address.
ETH is doing very good job against bitcoin because of Tokens.

yes i agreed we need blockchain technology in our daily life, So many people are talking adopt blockchain technology in elections,
It's is more secure than any other system right now.
It's is very very  difficult or impossible to hack blockchain technology.

No that's not true, Do you think 21 millions bitcoin can control the world economy, that's not possible.
World GDP in usd dollar 75 trillion dollars than how we can say that bitcoin can control world economy.

I think Bitcoin is playing important role in modern world because people are more interested in bitcoin earning.
because Some of websites start accepting bitcoin as payment and also govts. showing interest in bitcoins like japan legalize bitcoins.

I don't think so, because when we converted btc into cash currency than we paid some taxes from amount.
One thing more govt. is not fool , maybe maybe govt  make some rules for exchanges and apply some taxation policy for converting btc into cash through exchanges,
