I noticed a trend in crypto, after a coin/token is listed on an exchange usually the price starts high like 3x/5x the price of the ICO and drops very quickly sometimes below the price of the ICO. "ex. See EOS chart"
I assume airdrop/bounty members are the main cause of that, wanting to get rid of the tokens they got for free asap

Taking the above into consideration and in case you want to hold on to your tokens for the long term, you may need to:
-Sell as soon as the token is listed or don't sell
-Don't sell 100% of your position. 20% is 40% is risky enough
-Do not sleep until you buy back the dip, basically making x% more tokens in few hours/days

In this particular case "PCL", I would probably hesitate to sell any tokens at launch because it is very undervalued, wasn't advertised enough,
plus "the big money" US and Chinese investors couldn't participate in the ICO and maybe just waiting to buy on the exchange
