Hi there nappoleon! That is a great idea, I just hope that the transaction fee to transfer the crypto from your wallet the Uber driver wallet is free or in a very minimal rate. Would it be nice if the Uber app it self have a feature to add tip from the driver. Or any excess from the rate will automatically be tally and count as tip, thus Uber raiders can view back their total tip given in all of their trips. Additionally, it could be better if we could add funds to Uber app through cryptocurrency.
