I think both of them are interesting gifts and your friends will be happy with that. Give your friends 1000 XRP, and save 5000 ADA in the personal wallet. If I still had money, I would like to invest my money in ADA, stellar, ripple.
if I still have enough capital, I will also invest in the coins you mention because they have great potential to rise because they are strong coins. they have good resources to continue to increase.
