Ethereum is the basis of many projects known to all and is for me the first to create a true and first revolution in the world of cryptocurrencies (after Bitcoin), its possibilities are enormous, it offers smart contracts, creation of tokens and much more, although it also has its flaws of course, flaws that will be fixed (or so we hope) with the launch of ETH 2.0. I've never liked Litecoin too much, it doesn't do anything that Bitcoin hasn't done a long time before, and when Charlie Lee sold all his coins seemed to me like he was saying "there you stay".
