If Bitcoin was legalized in Bangladesh, I would take a payment system through Bitcoin with a pizza restaurant.
But my dreams will remain dreams because Bitcoin will never be legalized by the government in my country.

Don't give up on your dreams yet, use this period to make your business very popular in your country and be accepting payment in fiats which is your local currency. You can't know what the future holds because some countries that have accept Bitcoin now wasn't considering it few years ago but they're accepting it as a payment method today. Also has your government banned bitcoin operation in the country or not because this is what will determine if you can accept Bitcoin without breaking the law.
Your country is an Asia country and they're all looking up to China because if China accept Bitcoin and it favours their economy other Asia countries will do the same. I believe a time will come in the future when no country can deny Bitcoin as an alternative currency in the world.
