Should i invest certain amount on TRX and Cardano ?
just need opinion.
I am not familiar of that certain coin but if you think that it is the best thing to do then you must give a try. But if I were you I would going to invest in bitcoin or ethereum because this coins are proven and tested.
You may not heard about them but you can check them in the marketcap to see their status and what are these kind of tokens. But it is better to have more tokens in your portfolio so that you can easily diversify it to cover your losses to different altcoin.
Those two that you have mentioned are already in the market, so if you are hesitating on investing on it then don't invest on them. The fact that they are already in the market is enough for you to trust them, just keep on checking their prices and check their market supply and volume for you to know if they have the chance to pump or not.
