I think investing in XRP is not a problem even though it might be considered a slave, because it looks XRP is more popular and has faster movements. XRP is a short-term investment and this will look more profitable. ADA also looks cheap and more affordable, only it seems less than optimal to be able to process it.
XRP has progressed several times and this proves that XRP is feasible to have, especially now because there are many companies that use it to allow prices to rise.
but the ADA coins are also pretty good in my opinion, it's just that we have to invest a large amount if we want to make big profits.
