I always said that the best altcoins to invest this year is the ethereum and yes because I really believe to this coin that every year the price will grow because more companies have interest to accept this ethereum to their business like payment and investment to their project or the platforms they build and as of now I guess Im right that it is best altcoins.
There will be lots of people saying that Ethereum is the best coin, but I am still looking to other coins like Litecoin. Looking at the current Litecoin price on CoinMarketCap reaching $ 140 this could potentially be like Ethereum and the price is high. Maybe Litecoin will be the next coin like Ethereum. this is my own opinion
Besides the cheap price of litecoin, transaction fees are also quite cheap and for fast delivery confirmation, unlike etherium which costs a lot to process transactions quickly, and in my opinion Litecoin is indeed one of the best coins of the year
