I think you should divide your briefcase to have 70%/30%, 30%/70%, 80%/20%, 20%,80%, 60%/40%, 40%/60% of risky/stable coins.

Such coins like BTC, ETH, LTC, OMGCAT and etc you can keep as stable one and new ICO currencies as risky one. These like divided in wallets you can always build on your own

BTW, thank you for interesting in this project
