Investment decision

Hi guys,

I hold in my portfolio $ADYEN (-0,21 %) with an unrealized gain +75% and I was thinking about selling (right now is 3% of my total portfolio).

Reason to selll:

• I would like to decrase the number of holdings I have in my portfolio and reinvest the amount into Visa or Mastercard (I have an opened position on both these stocks right now).
• Adyen is a very good company, but does it have a moat? Competition is a high risk factor in this field (Braintree from Paypal, Amazon Pay, Shopify pay, Klarna and so on). It seems that every day a new online payment transaction company pops up.
• Can it keep this pace of growth with all this competitors? I am not so sure.

Reason to keep it:

• High ROIC
• Online payment transactions in the future are only going to increase
• Good revenue growth
• Very profitable
• International expansion in Asia and America is at the begininngs.

Should I keep it or sell it?
