The world of crypto is cruel and unpredictable. If you've just hit a scam once and have been disappointed, you better back off, because in the future you may come back to meet the ICO scam not once only once. I have faced several times with scam ICOs, and have faced several times with failed ICOs. In fact, once also follow the bounty of ICO is quite successful, but got kick from the telegram group which joined the telegram group is the general rule.
