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.
So it will go up based on the fact that it has only given a 500% roi?
The devs really should reconsider introducing negative merit.
OT:
Polkadot is heavily overpriced. Market cap of 15 bil $ is waaaaay too high. However, with so much liquidity flowing into cryptocurrencies right now, the price will probably still go up.
And on what basis do you say Polkadot is heavily overpriced? while the current Ethereum price is $1,258.95 and Ethereum ROI is 44417.52% (but people don't say that Ethereum price is heavily overpriced) and what can make you say if "Market cap of 15 bill $ waaaay too high ", because if you look at the movement of market cap, then you will know if market cap continues to increase, so do you think market cap should not continue to increase?, because you say market cap is too high, so what is the ideal market cap in your opinion? and how do you calculate market cap is too high, too low, and ideal?Polkadot is heavily overpriced. Market cap of 15 bil $ is waaaaay too high. However, with so much liquidity flowing into cryptocurrencies right now, the price will probably still go up.
