No, it do not depends on people but it depends on spreading the news and knowledge about, the more we spread the knowledge about it the more will people trust on it and will support it, if some do not have got enough knowledge about it then he will not rely on it.

I think the fact that they dont know about it.

i think about bad media says about bitcoin, will not make people stop. it make other people not interesting with bitcoin

That is true.. we really need to spread the words about bitcoin in anywhere we are...many people still don't know about this...sometimes even in a family only one knows about it.. 

First of all, this coin is not so much famous on international level. Mostly people don't know about this currency. And its price which is going down, also a cause of stopping people from using Bitcoin.

Imagine you need to pay someone say $2000 that painted your house or performed another service.

And you wanted to pay them in BTC

And they heard of BTC and have no problem with the concept but never used it before

When you realize what you have to do - the explaining, the convincing, the handhold, how much time it takes you get them onboard and how much time it takes them to go through the process and have it converted to fiat in there hands... 

first, we cannot buy anything by bitcoin, we just can buy some stuffs as long as the seller accept bitcoin

second, in some countries bitcoin has not been totally legal yet

Many here keep denying that it's difficult to use. That's a fact but what it's worse is that there's actually no problem to solve. Bitcoin doesn't do anything better than Paypal or CCs. Common people don't need Bitcoin in their lives unless they want to invest long term. People here mentioning Paypal is refundable as if was a disadvantage? you think that's a con for common folks?  Do you think my mother wants to use Bitcoin (which is non-refundable) so the minute she makes a mistake she will lose all her money? Really? Because she will make that mistake sooner or later I guarantee you, there are decimals, authorization keys, brain wallets, address as long as long as line of code, qr codes, and you think being non-refundable is a plus? I think Bitcoin is a unique technology don't get me wrong but is in its infancy just as the internet was in the early 90s, it's still just for curious and tech savvy people. In this case it also attracts investors and traders.

i believe really that this all news against bitcoin is from competitors ,trying to stop bitcoin adoption that will happen soon or later,its too late to kill bitcoin. anything can be connected to the black market and since the beginning of time people did illegal things. If not money then salt, gold, feathers, whatever. Now bitcoins. The medium is not the problem. But I understand - bitcoin is powerful and the banking system is afraid of that. It's just like the oil industry trying everything to stop alternative fuel, because they would lose money.

it's too volatile, there is no real market, only for nerds and libertarians. Just a niche
