For me, i think i would give chance both bitcoin end ethereum equally because i really believe that they surely have a great future. They both strong and reliable. Its actually hard to choose only one.
agree with you, Bitcoin is the king of coins he always occupies the top position of many people who have understood his superiority and so many interested ones. Ethereum is also a reliable Altcoin, it has great potential, for a very profitable long-term investment, both have the power to survive. if you have large enough capital, it's better to buy Bitcoin now because now the price is still cheap if you still have more money please buy Ethereum.
