I would choose hold ETH because it has the ability to duplicate while BTC is difficult to duplicate and the current BTC price is quite high
That is a good opinion. With the present price of eth which is much lower than btc, it has a big opportunity for price to increase .under a high demand, price can go up strongly and eth holder may get big profits. Price of eth is more stable than btc right now while btc is higher and fluctuative.
