The centralized/traditional banks are not always happy with the proliferation of cryptocurrencies in the mainstream nowadays, and the fact is they consider it as a threat to their financial services and businesses that's why we can expect more setbacks regarding doing transactions with some Banks, but I think not all big banks are against with cryptocurrency, because some big banks in my country are already embracing the blockchain and crypto innovation. that's why whether they like it or not traditional banks must accept the fact that they must co-exist with the crypto-based financial innovation and services.
