Im not sure what you mean using the word "bank", if you mean real bank... it's a long and complicated process, but you can establish & get "Financial Institution" license covering the whole EU easily with that amount, providing that you have some people in your team with the banking expertise. It allows almost all traditional banking operations. Process takes about six months, and requires about one million eur capital.
which countries in europe you can get Financial institution licence? one million eur capital?
Everywhere...even though most picked jurisdiction are UK, Cyprus, Lithuania, Estonia. And you don't even need 1M any longer!
Check "Mistertango"....thanks to the PSD2 regulation, they do provide "typical banking services", account opening, payment processing in both fiat and crypto, and they only had to comply with a minimum "capital requirement" of 125K euros for its licensing as "Payment Initiation Service Provider".
