i dont really get what your trying to say but i can say that both etherium and bitcoin are verry good coins and each of them has their own pros and cons but in terms of profitability id say go on bitcoin because as you can see most people are already earning on it in a matter of time due to its rapid growth yet etherium is also a good choice and the best alternative option if you want to spread your funds to for a better profit.
Yeah what he said. Keep in mind that all the people claiming that ETH will tank don't understand that the ethereum platform is used in over 80% of all altcoins. In order for altcoins to have ICOs or donations or distributions they rely on ETH network and protocol. The amount of ERC20 tokens listed on CMC is staggering. Just goes to show that Ethereum isn't going away anytime soon, but BTC is the mother of all crypto so there's no judging BTC will go away anytime soon. Either is a good investment.
Even if either of them crashed they would bounce back. Not sure if anyone remembers Mt Gox, but after that a LOT of people lost hope in BTC and assumed 1.2k would forever be its ATH.
