I invested in Polkadot and already earned 50% 
congratulations, but have you sold your Polkadot yet? Because now the price of Polkadot has risen even higher, but if you haven't sold your Polkadot then you better still HOLD, because I believe the price of Polkadot can still increase even higher, so my advice is if you want to sell your Polkadot, then you better not sell 100% Polkadot that you have, because the price of Polkadot can still increase very high and give you a bigger profit.So he should hold because you “think” the price will go up? Please elaborate on why you think it will go up. What a dumpster post.
