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 can't convince you to buy BTC because I am more of an ETH guy. But that doesn't mean I hate BTC. I used BTC as payments. Before I need to secure a bank account just to purchase online. Now more and more ecommere is accepting bitcoin as payment. Eth on the other hand is very important utility, because it houses almost half of the platforms currently being built of running. BTC is the top dog, but ETH is the more important, because without it, half of the market will also die. Just saying
