I think 50/50 is good either bitcoin pr eth. Because those two are leading in the ranks and good reputation also soon ethereum will be more productive because the popularity of it is beggining already and bitcoin has good reputation as well so its good to invest right now.
There is a world of difference between bitcoin and ethereum,first it cannot be considered as a currency,it is a mere token creating platform and how long it can go is a very big question,the price has risen considerably without a doubt,but the question remains,how long it can go and will we be seeing another rally with ethereum,the best bet is always bitcoin.
