BTC is the king. Others follow the king. ETH is future money too but to compete with btc it takes long time. Now eth price is 567 USD , hope it will back to 1000 USD. More tokens will climb up to. ICOs will be refreshed if the price of eth increase again. Most ICO based on eth token erc20. Only few ICos use other platforms.
