The answer is a capital NO! Crypto assets has not been recognised as legal tender by almost all economies world over. It is not possible for any embassy to accept It as proof of financial asset. If you have such assets I believe your best bet will be to convert those crypto assets to fiat currency and present your bank statement to the embassy.
Thanks for the submission, but I think stocks , real estates and cars are accepted by embassy to evaluate how someone is worth in order to grant visa, so why won't crypto assets that is even more liquid than stocks, real estates or cars.
Just as as he said,
cryptos aren't really recognized as legal tender by most of the countries but stocks, real estates and car are. I think the main reason for these is cause it's tangible, is my term correct? and still, bank can get a hold of these unlike cryptos. Surely, asking the embassy through the phone would be the best answer.
