I don't like it when they launch these ICO?IEO without more information on any project. Even the project has not any official website. There work is only set an ICO/IEO hold the ico price for a few days and suddenly dump the coin 50-70% in price. This behavior is not professional indeed.
Nowadays crypto investors are enough experienced and most of them know where to invest there money. There was a time when people were so interested about ICO tokensale because it was really profitable to purchase some tokens in low price and sell 2x,3x higher after getting listed on exchange. At that time investors were not enough careful about team, whitepaper and project background. It was like a addiction to join any tokensale and wait for listing. After facing big smount of losses people start to leave this field of investment.
In recent time scammers have changed their old techniques and by dishonest trading platforms help they start another game. This time they know they can take the advantage of shady trading exchange users and start to list their IEO projects on exchange like Yobit, crex24 and much more. Exchanges are well notified that some projects will not last for 3 month in real but they continuously giving their support for a handsome amount of listing fee and total sale percentage. There is some common activities which are done by exchanges to attract investors on any IEO project. Such as,
1. Regular IEO tokesale notification to registered users.
2. Announcement on their social media but don't care about people's reaction.
3. Disable token trading for buyers for a limited time to create fake price bump.
4. Purchase all token by their own and declare all sold just in 5 to 10 min.
5. Unexpected price bump and sell all token in high price.
6. Using trading bots for keeping the trade live on a particular level
Finally investors make their entry and token price drop down to grave. Personally i believe some of these exchange launch their own ICO/IEO project and make investors fool. All they need is just some easy money.
