Would you invest in well established cryptos or new tokens?

Would you invest in well established crypto like Bitcoin / Ethereum or XRP etc., or choose some new project?
I have invested / traded established cryptos long time, but now it seems that there's only moderate profits available with high risk... so, I have changed my strategy, and started to go through new projects even at presale stage, and if I feel comfortable with them, I will buy @ presale. of course it's super-high-risk compared to investing in established coins, but i think also rewards could be very different.
