I'm pretty new to this, and after researching a bit, I feel like ETH is going places and has far fewer barriers to expansion that BTC. I want to buy and hold some coins, and as of now i'm leaning towards ETH. but I can't ignore the fact that bitcoin seems like top dog still... so convince me to buy BTC instead of eth. Give a reason besides "first movers advantage"

I have bitcoin, of course also with ethereum. what's more eth prices are currently down sharpest compared to other altcoins. every speculation is always followed by market developments, situations and conditions. you can do many ways and plans in the long run or short. determine immediately
