I am not sure with the three coins the price will be high at the end of the year, I believe more in the ETH for now, I believe at the end of the year or early next year the price of the ETH will soar.
for long-term investment I still believe in ETH. that in my opinion.
All those coins are just some sort of shitcoins that should never be much invested in, but for the benefit of doubt, one can just find some change that one does not have any need for to invest In them and just forget about them, and maybe in future when they have a goal and purpose, they will grow and increase in value, but for now, I think that Ethereum should be one of the major coin that our attention needs to be on.
Ethereum coin might be looking like it is down now, but with the releases of their Ethereum 2.0, I am sure that they will be revived again, and that would be released next year 2020, so when you see Ethereum and those other top altcoins, we really need to be prepare for them for the future, especially anytime from that 2020.
