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.
Indeed. Thats the aster for this question but it is never too late to ask to the embassy itself or enquire about this assets over the phone. I am adding the second line because there could be chance that wallets who has got KYC verified for the user then anything in the wallet is considered as your own money and it is traceable one. So thats just a chance BUT its too small to be true.
However, crypto assets really are virtual one and they dont belong to us as long as they are not in the bank statement!!
