You can invest some but don't assume that it will most probably increase its price to that amount.
But I am seeing that the price of ethereum is increasing so anyone who will want to invest in that coin will not lose their income and will earn a high profit even from that currency along with bitcoin but I have my money in bitcoin because I am seeing that the price of bitcoin is much faster than ethereum. If someone will want to choose one of them then the better option for them is bitcoin.
I think you are missing something. We saw how ETH price grew x40 while BTC made smth around x12 or x20. So how it could be that BTC is faster?
