I think 2018 is a new piece for digital coin hunters. The prediction of the coins that will skyrocket in 2018 is Ethereum, Dash, Ripple, Monero, Litecoin, these coins in addition to the lightening of the transaction process is also faster. and will expand its wings in this 2018.
But if you take one of the latest coins, I think Etherium can grow very fast. Of course it depends on how exactly this coin will be implemented and how many projects and investors will support Etherium and this prospect is very good.
You're right mate, as time goes by many crypto currencies increase as most of them rely on the bitcoin's value. Well, obviously bitcoin is the dominant for all that makes everyone amazed on its performance as it hit almost $20,000. Also, the performance of ethereum that it suddenly increase as the start of this year. Thus, for me bitcoin and ethereum is the promising coin for this year 2018.
