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.
20 times will happen, but we never know how long it will take to get their, my target is even bigger than that
but without other coins, my usual target is always x100 because I know it's possible, but if you invested bigger, you'll be alright with x20 though.
