For me mate the best to invest is ethereum great choice from your(ETH) we should know that their price now is very cheap but I still believe if the time of bullrun comes keeping etheruem is the best to get huge profits so my priority to hold and kaeep in my wallet is eth. TRX, CARDANO and DASH is also have a big potential to get uprise in the market that coins you said I one of them for my second priority to aa my invest(CARDANO).
And now ETH is getting cheaper again. I am already invested,,, and now price needs to go 2.5x for me to break even haha,,, but yeah no worries about ETH for me, they will make sure it is ready for use the way it was intended when 2.0 is finally up and running 100%. And then when Bitcoin price also improves, ETH will be the first to go back to ATH.
