I am holding Polkadot from the beginning as it has already giving me much profit and for long term it is very beneficial. If you are a long term trader and have the ability to hold long term coins then it will give you much profit in the coming days or month. So I will prefer Polkadot. It is the best coin.
Polkadot, this is one of the altcoins that I see that's being liked by many.
Even I'm not yet holding it, with those people that I've seen suggesting this coin and it is what they're holding makes me want to hold this coin too.
I did my research on polkadot and I also think that it's good.
