i disagree with your opinion mate,
because polkadot is a solid and promissing altcoin,
and i believe this coin will replace usdt and become the TOP 3 coins in cmc sooner or later, just like this coin replaced xrp
I think like you too, I've been following DOT since it was only around $ 5, and see how I feel now. Personally, I have yet to sell any DOT and I am still continuing with DCA Polkadot, TOP 3 place is completely worth what DOT has shown.
