i wonder there is a better source to find about ICOs that will give 3x ,5x profit in short term.lot of ICOs in these days are scams or don't have real working product.and also they go below ICO price after list in exchanges.but i want to invest on real ICOs that have working product and give me 3x,4x back for my investment
Yeah it is important to find ICO with a reliable source because many scam ICOs. you can try look at the ico rating site like icobench, icotracker, etc.
Some peoples even make spreadsheet with a list of ICO and their measurements about ICO value.
