I think yes you can get profit in ico especially they will promise to sell there tokens wit a discoun but before you enter in this fied you need to analyze there white papers , if the dev are kind and transparent and the last look at the result of every bounties if they payed all the participant who actively participate thats how I determined a good icos + active in social media like twitter and telegram . But in some case you cant assure if its legit or scam .
