I also invest in both, litecoin and ADA. But honestly I prioritize Cardano ADA over Litecoin. Everyone definitely has their own considerations and analysis, and I also agree with you that we should have both because these coins have the potential to be held until next year.
I also used to love and invest in LTC in the bullrun 2021, but LTC did not bring me significant profits. Litecoin currently does not have any major updates either, its ecosystem is quite boring and not as strongly developed as the Cardano ecosystem. Therefore, LTC has not been in my investment portfolio this bullrun, while ADA continues to be a safe choice thanks to new projects, new proposals and new growth potential. I hope the ADA token will once again create a strong price increase and attract the attention of the entire crypto market and soon return to the top 5 on Coinmarketcap.
