Holding up to both coin is good,  but one needs to consider the profit aspects also,  we all know that these two coins are the giants in the market,  they are long term coins,  but having a lots of units is the goal so as to secure huge profit,.

It's much more easier to accumulate more units of ethereum than bitcoin,  and ethereum is currently so low in terms of dollar price and Satoshi value,

Ib think going in for ethereum at this time around is a good decision
