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 ?
And one more things I wanna know that how can I chose a best budget friendly hardware wallet?
If I were you, I'd avoid using/buying hardware wallet. Just use Electrum or any other solid reputable wallet that should be enough. If you're particularly security conscious, set up an air-gapped device. That's not complicated to do, you should be able to find some instructions here on Bitcointalk.
