For me i choose bitcoin because bitcoin is welknown coin and the price is very big and the security so very strong and safe to invest and it is good to buy for now because the price is cheap buy and hold for the longterm.
I think ethereum can also be used as a long term investment, and ethereum transactions are faster then compared to bitcoin. fos safety also nice ethereum. so I think both coins are good to buy
I think so too. Now these are the two most reliable coins for investment. And it's better to invest now, while the price is low.
