Does it affect the tax authorities to have a Rebellion account?
If you are a Spanish resident and you have more than €50,000 in your account (which is impossible given our account limits!) on 31 December, you will have to declare it on model 720.
Is Rebellion registered or "connected" to the Bank of Spain?
Rebellion is registered with the Central Bank of Lithuania, which is directly connected to the Bank of Spain. So indirectly Rebellion is connected to the Bank of Spain but not directly.
