I think altcoins will be very interesting in the future.
as more and more people come into crypto some altcoins will rise a lot that you don't have on the radar at the moment.
just wait and see, that's my opinion.
There may be some coins but it's hard to believe that any coin will be able to beat bitcoins. I keep an eye on a few altcoins but I don't feel any of them in the present day will ever be able to take over bitcoin.
I agree with the fact that there may be coins which are out of radar and will give a better return in terms of investment than bitcoin.
