Tron is the first name which comes to my mind as it has always been disappointment for me though I had given multiple chances but it failed miserably. It's better to go BNB and other top coin instead of Tron as the dev team is least bothered about further enhancement. XRP was once in the same list of altcoins which I wouldn't buy.
I think I have the same decision with you. The two altcoins you mentioned have only been top coins but have not shown that in price increase. Tron have also disappointed me when I thought it would rise with the rate other coins rose from the bitcoin halving bull . Ripple also have been there and have barely risen close to $3 or around that despite the hype that they get. I think trying coins that performed at the last bull will be a good investment like dogecoin for example but not an investment advise .
