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 won't say that etherium is not a good crypto because it is. Etherium is also profitable as an investment just like Bitcoin. But knowing the capability of Bitcoin particularly with the increase on its msrket value, surely Bitcoin is way better than eth. Just try to compare their market statistics and decide for yourself which one is better.
