Yes, many countries are not adopt bitcoin as their legal currency but it is not a big issue as bitcoin is a decentralized coin. Most of the time I sell bitcoin for fiat currency and some times I buy from online.

Bitcoin is not legal in the country where I live.  As long as I've been involved with Bitcoin, I haven't had any problems selling or using Bitcoin.  I can sell bitcoins to local buyers and get cash if I want.

I'm pretty confused with your question if it's illegal to use a Bitcoin on that country I wouldn't use it at all.
but of course I will try to avoid a country where cryptocurrency is illegal but if I'll be a tourist I'll convert first my Bitcoin to fiat to avoid using cryptocurrency while at the country.
But if you are talking about in my country well it's legal on where I'm currently living but the not many people are using it since they are not familiar to cryptocurrencies.

In my area, bitcoin is indeed illegal and the government has said that the use of bitcoin in my country is fine, but if there is a risk it's not their responsibility like that, we can still use bitcoin in assets but still in any transaction it is illegal to exchange it to fiat first and some online tokon services still don't provide payment with bitcoin.

But still bitcoin can still be used as an asset and your investment in the future, but I think that in the future it will be adopted again after the times that continue to increase.

Heard some news also that the government will use blockchain as its network.

Amidst this pandemic, I only hold some of my bitcoin and monitor the market. It is really hard to spend bitcoin and trade it because of this crisis and I'm looking forward to trade it when I think that I'm on the right time. I mainly use bitcoin as an investment and I never spend it for some other sustenance purposes for this quarantine. Also, there's no bitcoin ATM near our place and it is hard to utilize bitcoin when buying my needs in daily lives. Just hold and be patient, be observant and do your best to fight volatility in the market. I know that I'm not the only one who are struggling right now due to pandemic and most of us are suffering and forced to spend bitcoin for our necessities.

When bitcoin never yet legalized in my country, it hard for people to make use of bitcoin in the country. I will never forget 2016,when our government impose the law to the citizens of the country, if anyone caught with bitcoin or wallet shall be jail for 10 years. Many fell victim with the law on ground which make them to spend ten good years in prison because they were caught with wallet full with coins.
At 2017 our government now come to discover that bitcoin is not a scam but a good currency which anyone can use to invest and make a good profit. Bitcoin was fulling legalized in the country march, 2017 which really give all the bitcoin user joy and a big celebration in the country that make the government know how important it is to them to improve their businesse mightily in the country.

Bitcoin is a good investment for those who really understand how it work in the areas of investment. No taxes is pay to government before you can start investing in the country. Your bitcoin is your bitcoin and your wallet details are well safe.

I use bitcoin for making online purchases and also for buying gift cards.

in my country Bitcoin is still not legal, but I still invest in Bitcoin and only use it for long term investment, because I believe that someday big countries will start to believe in Bitcoin and legalize Bitcoin as a digital currency, so my country will definitely legalize Bitcoin as well and not only my country, but I believe almost all countries will legalize and use Bitcoin as a digital currency too, so the price of Bitcoin will definitely increase very high and of course it will give me a big profit in the future.

There are some cryptocurrency users who live in a country where bitcoin is considered as illegal. OP is talking about those countries which bans bitcoin from using and patronizing by the citizens . Some government in different countries are afraid of what things bitcoin do that's why they labeled bitcoin as illegal. Too sad for those people out there who are interested in bitcoin but needs to limit the transaction they are making so that they will not be traced. In our country, it is a good thing that I am unable to experience this because our country is open for bitcoin though it is not yet formally legalized.

I have no problem using bitcoin here where i live even if it doesn't become legal everyone can use bitcoin as they wish there are no government restrictions here there is no problem in buying and selling but bitcoin is not yet legalized in many countries which is very sad. If they only knew how to use bitcoin properly they would never avoid it bitcoin is more profitable than fiat currency in our country it is very easy to convert bitcoin into fiat currency.
