If not bitcoin, my top 2 altcoins that you should be investing in right now is ethereum and ripple, here's why ethereum and ripple, first of all, ethereum is really neat, and slick, it has fast transactions, and is secured, this is why ethereum lately has been successful. The first thing about Ethereum is that it is not just a digital currency. It is a blockchain-based platform with many aspects. It features smart contracts, the Ethereum Virtual Machine (EVM) and it uses its currency called ether for peer-to-peer contracts. Then we have ripple, also a great cryptocurrency, hence it has secured and safe transactions, and it has their own unique way, Ripple is the name of the company, and XRP is the name of its coin. Ripple was specifically created to facilitate a now-outdated system of international transactions, comparing bitcoin to ripple, ripple is actually a private company, security for investors is what they seek, and the cost of transaction is great, rather than transaction cost of bitcoin, these are the reasons why ETH and XRP are one of the altcoins that you should be investing right now.
