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 can try to read all of the whitepaper and the background of the altcoin for you to know if it is worth to invest in. But as of now, after i googled your question, you can try to invest in cardano. Based on what i have read in investinblockchain.com, it is the first fully open-source blockchain to build using peer-reviewed academic research. Well try to check that out.
