Which two companies would be unstoppable the next few years if they merged? Let me start:

$MCD (+1,29 %) with their brand and number of restaurants, but with the quality of $SHAK (+1,11 %) burgers.

or

$COIN (+4,25 %) and $CHWY (-2,19 %) - the two already have the same logo anyway - plus Tier products are easy to pay for with the crypto wallet. Simply Meta.
