There is no country in our country, Bitcoin and cryptocurency are not legal in our country. So it's impossible for me to buy with BTC.
In addition there is no BTC payment option. Yes, hopefully things in our country will be legalized by bitcoin.
Most of the countries nowadays doesn't use crypto as payment because operators of gambling prefer cash as their mode of financial system payments. Its hard to incorporate this thing to digital currency since worldwide doesn't recognize crypto yet. Maybe it took more time to make crypto adoptable for people in order for national lottery to use bitcoin at their comfort so that transactions of gambling bets became more accessible at any place or time.
Our country hasn't got any legal statement supporting the use of bitcoin as well upon the opposition of bitcoin usage. It all happens with the buyer seller risk, if someone is interested he could explore and find a person selling the national lottery in return of bitcoin. From my experience it is really an impossible task at present. Things could change in the near future.
