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" 
every thought of the person is very different, and for this choice agan it is fixed and steady yes bitcoin no problem. because all the decisions are also in your hands. so think well first. because bitcoin is also good at gain and its usage is quite easy. but finding bitcoins is not easy.
