I think Facebook should have started with a simple stable coin concept linked to the USD, and bring it low-key to the market. Later on they could have expanded it with other underlying assets and also new services. By taking on this big approach from the start, shouting it loud as the solution for the unbanked world, they have shaked the old world too much. Not a wise approach. If I was Amazon, start with this low-key approach of bringing out a stable coin first, only linked to the USD. In this way you stay under the radar till you are becoming too big to be attacked.
