If you are not a financial expert or advisor, you should not give indiscriminate advice, especially on matters in which you have no experience. PI is currently trading at $2.7, if someone took your advice and sold them 2 days ago, they must be regretting it for losing a significant amount of profit 
.
.But few hours ago the price is at 2.9$ but right now it’s on 2.6$ level and decreasing. This token is high volatility which means you can even sell below 0.6$ level if you are not lucky enough to sell on time.
This token raised a red flag due to mandatory KYC to all their miners while other popular exchange doesn’t list this until now despite high demand from users hype.
You’re correct that we shouldn’t give financial advice but it’s not bad to give a warning if there’s a red flag on a project like what happened to Trump coin.
