so true. I also thought that it would be a competitor for bitcoin, and eth prices had also skyrocketed. but, it did not last long, and when it becomes dimmed. I believe bitcoin will remain the coin of the first, and will be the best coins. I still doubt if there altcoin were able to offset bitcoin or not. altcoin always dimmed when there is a new altcoin, which has a high popularity.
As long as those alternate cryptocurrencies weren't too counting on bitcoin on its every aspects such as ICO, Value of the coin, much more inside its project then it could surpass and probably take over the first place beating bitcoin. Otherwise, it's not going to be happening. this tradition already continued from a few years ago, now it's proven none of them could take over the first place, it's really clear.
