Is it safe to prove the principal by deposit when traveling abroad?

there is no need to prove that the principal is safe. The main purpose of the deposit certificate for traveling abroad is to prove that there are enough funds to pay for the travel expenses, so as to ensure the smooth entry into the destination country. This requires proof of assets in the bank account to prove that there is enough balance in the account to pay for the travel expenses. These documents are to prove the economic strength and the feasibility of the travel plan, not to ensure the safety of the principal.
