I am from a country where crypto currencies are strongly legalized. I know about the hardware wallet security it's best for the long-term bitcoin holder. Now is there anyway to import a hardware wallet to any country where crypto currencies are illegal ?
What do you mean by import a hardware wallet to any country?
You can buy a hardware wallet and use it to store cryptocurrency or send cryptocurrency to other wallets which can be hardware wallets or hot wallets or cold wallets or even online accounts like centralized exchanges.
And one more things I wanna know that how can I chose a best budget friendly hardware wallet?
Hardware wallets are not your only choices as you can use free open source non custodial wallets. You can use those wallet softwares to set up your multi signature wallets or cold wallets. They are free so if your budget is not enough to buy a hardware wallet, you can consider alternatives.
