Found this amazing table on twitter. Great way to see where we are at currently with the top ICOs in regards to returns at this moment.
Looks like OmiseGO is crushing it! Qtum has crawled up form nowhere to a crazy markecap. And Civic just made in time to be listed high on this list.
Another note is that the lower ranked tokens are not listed on popular US exchanges like Bittrex and Poloniex. Which could mean some things things for those tokens not listed. They will be classified as a DAO token and will be delisted or never listed on US based exchanges, this has happened with distr0x token and Bittrex so some degree. Or when they are listed on US exchanges they will likely find more investors.
Conclusion
Buy ICOs looking to comply with US regulation. Or hope to find a large pool of investors elsewhere in the world (China, Japan, Singapore)
