The steep fluctuations is the major factor that keeps most users away from bitcoin usage. Also users don't have good knowledge and learning about bitcoin. When they know clearly, users will understand that those fluctuations were not a matter.

Maybe some people just do not believe in the future and do not think that they are going to see as much profit as they can. I am not going to stop using Bitcoin because for me it has become a part of my soul. 

Unless people have come across certain rules and regulations on using the btc by the government, people would use the btc.  People love to use the btc for many things. It is just the fear that is stopping people to use the btc.

You are right almost all of the currencies are used for legal and illegal activities including bitcoin, but people are blaming bitcoin more because they are of the view that bitcoin transaction is anonymous and with that the criminals do their crimes to buy drugs and weapons while hiding their identity.

It's fear that's stopping people from using Bitcoin? People should be fearing the constantly decreasing fiat value. Their wealth is becoming lower and lower even though the amount of money that they have stored is the same. People should be glad to have an option as Bitcoin to store their money in.

all most every person is facing this problem. the lave of facilities the shopping centers. but hope that in near future all these problems must be take to solve these problems.

There are many companies that offer bitcoin debit cards but first, you should check:

• Are they able to send you the bitcoin card in your country because not ships worldwide
• Then you should check for the fees, most of them have different fees.
• Withdrawal limit, some have low amounts some high depending if you are using as anonymous or as verified user.

Some of the companies that offer bitcoin debit cards are: spectrocoin, bit-x, e-coin, xapo etc.

For people, it means choosing between a form of money that they've been familiar with for a long time and something that is new. Also, knowledge about bitcoin is not enough. Because, if they don't fully understand what bitcoin is, and its potential and  advantages, they really won't be interested in using it.

To make bitcoin more secure and accessible, new features and services are being developed. Improvements in these areas will make people more comfortable using bitcoin.

That can be one reason and other reason could be that they have fear of loosing their money in it, as many people feel that bitcoin is an scam and will not survive in long term.
