Hello bro and sis, can recommend me some new altcoins, which you think are great project can invest some when their ICO and earn triple or double 
You won't get too much advice on rapid profits...nobody can predict what will go to the moon.
There are 2 very worthwhile investments right now.
1. Privcy. Great community, well supported by developers, airdropping right now and set to only get bigger and better.
2. Electoneum. First crypto to really tackle the idea of using coins to pay for everyday transactions. Their new instant payment system is beautiful and the project is well supported. The price has taken a dive since the ICO but i believe now would be the best time to invest.
Good luck with your investments and hope you have great success.
