Yes paypal use crypto but instead of eth many users was expecting the TRON blockchain its faster cheaper and more used.
Eth transactions still too expensive i hope they start use TRON soon
Understandably, many institutions are gradually interested in crypto, and more and more big names have entered this market. However, the story that OP asked I think you need to re-research between ETH and TRON, not using the advantages of one but comparing the disadvantages of the other, in fact we see which one is more popular it will take precedence, if there is no special relationship then there is no reason to use TRON, moreover I also agree with many people that TRON is really bullshit.
