Yes, if you can hold it for the medium term, it is one of the best coins among the market's top altcoins. There are lots of reasons why. One of them is the loyal community. Yes, the polkadot community is so loyal, and we know it if we see dot aution. Not only that, but dothas a huge number of fans like Cardano, which will help to push the price up. So we can say "yes, it has a future and in the future its price will go up definitely." Still, if you want to invest, I suggest doing research on your own to find out which will be better for you.
