I agree on this list you have provided mate. There are really lots of existing cryptocurrencies in the market so it is really hard for beginners as well as for us who are already have a long time in this industry to choose among those numerous existing cryptocurrencies out there. But despite of that fact, for me Bitcoin is still the most outstanding crypto currency ever since. Among the list you have provided, the ones I have in my portfolio consists of Bitcoin of course and also include Ethereum that is for me still among the Altcoins have the great potential despite of the fact that it is still currently struggling to rise up its price. I do also hold into Litecoin for I do see potential into this coin. I have already heard and read some articles about Cardano and for me it is really fascinating and interesting that is why I am doing my current research and observation about it before deciding to get into it. As for now, those were my safe ground into the cryptocurrencies I hold that is based on my own preference.
