Thank you @audaciousbeing for all your advises. Paxful will be a great solution if I could open an IBAN account with them. Fortunately Morocco is not in their list of banned countries.
Does someone have an idea if I could open an account overseas in the country of my choice, particularly in Europe ? That will be my perfect solution I need.

Thank you @Javi_Anibarro for your quick answer.
It is a Finnish trusted website and I will try this. However it still person to person payment and I am looking for discreetly way out.

Hello all,
I am a new trader and I face barriers trying to turn bitcoin profits into pounds. Sales of cryptocurrencies are commonly made through platforms known as exchanges. But no cryptocurrency exchange currently has a relationship with a bank.
Fortunately European banks are more comfortable with the idea of banking with bitcoin companies. I gave the idea a lot of thought then I realised
there's no other alternative but to open an IBAN account as authorized intermediary between trading platform and my local bank--allow me to draw your attention to the fact that I am from Morocco-
Maybe you will ask the question is it necessary to use this authorised intermediary as a go-between ?
The response is YES. There is two reasons for this. The first Morocco worried about threat of cryptocurrency to its business. And the second all banks in Morocco use RIB as account identifier. So the go-between ensures transfer pounds from IBAN to RIB.
Here I face an other barrier trying to find a go-between not only he accepts transfer from/ to platform but on top of that he accepts customers from Morocco.
I would be grateful if you help me as soon as possible.
