I agree with your statement one should invest wisely. He/she should not invest on the basis of hype or manuplative ratings by some ICO rating platform. One should do proper research whether he/she participating in any ICO or participating in any bounty. Active or experienced project team is also very important in deciding whether to invest or participate in bounty. One should believe on its own analysis because money and time both are very important. Many scam projects ruin the ICO market to some extent but I would like to add one thing every project is not scam but due diligence is must.
