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.
