I think Ethereum will lead the currency market in the near future.
There is no near future to this. The chances of this happening is not zero, but a figure very close to zero. Hence you can say in the distant future, not the near future.
Which currency you think will lead?
If we did not believe in bitcoins to remain dominant and the lead cryptocurrency even in the next ten years, we will not be investing in it and want to HODL for as long as we can. Bitcoin is king and will remain so for the near future
