Although it's been a few days since Portal's Launchpool has ended and was listed for trading, I'll post my update. Portal started trading at approximately $4, but quickly plummeted and dropped below $3. Unfortunately, I was at work and wasn't present the moment it was launched, so I missed the opportunity to sell at a high price. I sort of went for it and sold at $2.5; thinking it through, I could have sold at a better price, but I wasn't too confident holding it. It has now dropped down to $2.20.
Unfortunately, no new projects have been announced yet.
The best time to sell a token is early if the token is launching on binance. That project was already hyped out and people started to sell off their holdings to take their investment out. Every project is not like TIA which has done something amazing even after it got listed on binance and started rallying up because of its ecosystem airdrop. Usually i don't participate in binance launchpool and i do like to trade them in their early stages but i always make sure that project has the holding value for long term.
