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" 
law of the 1st.. given the fact that btc still on the top.. law of the 1st explains that whoever is at the 1st its hard to beat, why?? here's my opinion i dont know if your going to accept this fact.. eth/btc trading pair compare to eth/usd pair.. and altcoins were almost connected to eth which gives eth value more.. but as btc price down, you cant deny that eth price also went down.. together with altcoins.. to sum up this situation.. eth or altcoins and other crypto currencies were affected when btc price went up or went down.. now think about this.. everyone wants to be rich and want to be the price to go up.. they should push btc 1st in order for them to reach their goal.. the more they push btc up.. the more they will rise.. i have so many things to tell hope i can give you an eye opening reason.. thank you so much..
