My country still dislike Bitcoin particularly USDT because they think it's the reason why our local currency value has suffered loss when it's obvious there fault for defending the currency when it ought to have been open free. Bitcoin is still like a mosquito to my government, they give temporary solution to hide from it and want people they are suffocating with high inflation to join their badwagon but the people that are already in Bitcoin can't be stop.

If the country doesn't dislike Bitcoin but aren't ready to accept Bitcoin as proof, why not sell some of your Bitcoin and give them bank statement as evidence. If they ask you the source of that source, simply show them your Bitcoin investment and they will not ask you further. Even if they further ask you the source of the money used to buy the Bitcoin, you can explain as long as you used clean money and your application should be granted.
