If you would just look at xem, it has solved the problems that bitcon cant solved. try reading and researching xem(new economy movement) you will know that it has potential to rise. it already rose 10,000% since 2014 so this means that it has a lot of potential to be one of the trusted coin in the future.
Yeah theere are many coins which are very good to invest at the moment and there are more than 50% of the coin existing on the marketcap are better than Bitcooin. In the future, we will see many coins rising and become a good force against Bitcoin
I think they are only getting pumped and most of them are just pump-dump shit and nothing too much invest-worthy and only a few have chances over bitcoins as a competitor but I still don't see any taking its place any sooner than a decade or two as Bitcoin has conquered the markets due to its superiority and will rule the markets as well as hearts of people for many more years.
