Bitcoin is Best coin every and all time is good to buy it
LTC is very good altcoin and will have good future (like Silver )
No matter that BCC is taking the second place by the price today the real silver among cryptos is ETH. On this cryer envy based a lot of other alts and tokens and I think exactly this function will bring the success to Etherum. This currency is my choice for investment which may bring millions among any others.
Agreed, ETH will be no doubt will reach a sky high limit. The base is growing stronger for ETH, and the value is again reaching $400 soon.
Also coins like Dash, Waves, Kick, Stratis are generally some good coins with a good buy for future growth terms.
Recently one great under noticed coin is Civic, its a identity verification related blockchain platform with good future glow. So its a good one but for risk takers only.
