Investing in e-commerce and fintech, MELI vs SE vs JMIA ?

MELI:

pro: strong economic moat, strong growth

con: political insecure (major revenue from its fintech “pseudo-bank “which is in grey area in latin america )

———–

SE:

pro: relatively political stable

cons: competition with Lazada (backed by Alibaba)

———-

JMIA:

pro: strong economic moat (no competitor in Africa)

con: Africa infrastructure is under-developed, geographic challenge of delivery cross countries requires long-term huge investment.

Any suggestions?
