Awesome product, great features and I love the constant updates. I really see Revolut catching on and expanding. I would have most certainly invested during the crowdfunding campaign.
My only gripe is, as an early adopter every other update seems to take away some of our perks e.g. Currency limits, ATM limits etc. Whilst I would be happy to even pay for a premium Revolut, I would also like to see some additional benefit for being an early loyal customer!
