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" 
Before when I'm new in bitcoin world, I thought that ETH and BTC are just the same but when I research everything that I want to know, I've discover that it has a big difference to each other. So for me, BTC is better that ETH because it is the only one where I earned a lot and it helps me especially in financial problems.
