ETH AND BTC ARE DIGITAL COIN AMBASSADOR THEN WHY OTHER COINS ARE ALSO IN RUNNING? 
I will buy the trx or tron or the litecoin either of this two , but for my opinion these ICO or altenrative cryptocurrency cant live without the bitcoin. And on the other hand I would and still invest.
I may choose DNC bar. As an emerging digital currency, DHC has plenty of room for growth and its companies belong to the emerging industries.
