But I would like to hear successful stories about people who invested in ICOs and made profit. Please, tell what ICOs you invested and how much profit you made, if you liked it and if you still look for this kind of investment.
Here's an interesting news article on Floyd Mayweather's endorsement of centra ICO. It covers some of the history of centra ICO as well as inconsistencies and lies centra have been caught in. Technically it is a success story. They have a lot of money and a celebrity endorsing them. Whether or not they'll ever deliver their product and follow through on their promises remains a question mark, however.
