There are so many tokens in the market, which means numerous possibilities.
It's not impossible that Bitcoin defeated by others some day, but there is no doubt that Bitcoin is still the best one now.
Maybe not the best one

There are various tokens and yes looking at it seems like it will defeat Bitcoin soon. I mean one out of X numbers of tokens in the market, but........
Did you think that many tokens survived after it was sold or dumped overnight?

How many of the ICOs coins were just mainly for the pit of bounty hunters that would just aim to sell it after it hits the exchanges?
There were many successful coins that still survived, somehow but the circulation or the trading circulation of the coin isn't even getting close even a half to Bitcoin for it to catch up to its price, applying demand and supply.
