Both cryptocurrencies are very popular and I sometimes invest in both cryptocurrencies and most of all I managed to earn from investing in LTC, but of course it all depends from your amount of money that you want to invest in these cryptocurrencies and of course at what price you will buy LTC or Cardano, well and of course at what price you will sell Cardano and LTC, and in general I always liked both cryptocurrencies for their rapid development and these cryptocurrencies have been bringing income to their investors already long time.
