Have you done your study and where do you know the margin will make big money? I believe it is your decision to invest more, which means the two currencies are each $5,000 to invest. It will be tough to recoup the money if you fail in that presentation.
I understand that everyone has their own portfolio in their purse, but I don't believe you should rely on only two currencies; there are still many coins that are more valuable than XRP and TRX.
