First off all, I'll avoid tron. The reason is same as op. Secondly i think xrp is the another coin. I know this coins made people millionaires in 2017 bull run but now it isn't looks to me for investment. Besides it won the court case but there are still many questions regarding their activities. Some articles indicates about future obstacles about xrp, which doesn't inspire me to buy xrp. And same reason is for tron. No controversy but a pure shitcoin and no clear sign is found yet for its future progress
You're right, Tron aggressive pricing at launch in 2017 caught the attention of many investors. Many investors have successfully profited from this opportunity. Scams are not leaving behind them because of which they fail to attract their investors. Although they have not yet been able to get out of the legal trap, they have continued to try. However, Tron's market value seems quite stable but there are doubts about its future.
