Imagine you had to choose only one altcoin for your bag. I can't decide between GRAM, LAW and Libra. The last one is the most questionable: it's popular because of FB but I heard it won't be profitable because of its features of stable coin. GRAM and LAW are great because of its technologies but they are not as popular as Libra. So...yeah that is my problem...And what is your choice?
Your choices are weird. And not just weird, these are not even top coins. As to Libra, it is not yet offered. And it is not going to be as strong as other people might consider. Remember that a lot of opposition immediately surfaced as soon as Facebook announced that it will be creating its own crypto.
ETH is the second in rank and first among altcoins. That is definitely my choice.
