Basically in 2019 there are also many altcoins that are still cheap, I personally will hold ethereum, ripples, neo, waves, ADA, omg and dash.
Those coins you mentioned has a potential, so if you will hold, it could probably give you some good gains. Actually this time is suppose to be a good year to buy.
Why? Because all are cheap now, you cannot find this anymore when the rocket starts to pump.
You know, bull run will come soon.
tezos in my opinion.
it took really good inest in ico. it is sleeping giant.
after cases i am waiting at leasst x20 from tezos.
