Ethereum! You can easily trade Ethereum for cash or assets like gold instantly with incredibly low fees. The high liquidity associated with bitcoin makes it a great investment vessel if you're looking for short-term profit. Digital currencies may also be a long-term investment due to their high market demand.
Yeah, ethereum is definitely a good altcoin to invest in. Same time, I think the price has really gone up for small investors same as bitcoin. I'd rather invest in those solid undervalued coins that expensive ones. Undervalued coins would easily give you gains in both long and short term. Look at the likes of Dent and Wink and Trx etc.
