Litecoin (25%)
Digibyte (20%)
Byteball(20%)
Maidsafecoin (15%)
Namecoin (10%)
Feathercoin (7.5%)
Ubiq (2.5%)
That would be my balanced but those are the currencies I believe have a future. Your opinions may be different but these all have solid credentials behind them. Also some sleeping giants here.
Feathercoin... I rest my case.
Still, I agree with most of this.
1. Bitcoin (40%)
2. Byteball (15%)
3. MaidSafe (10%)
4. Litecoin (15%)
5. Monero (10%)
6. I get lost in the world of shitcoins after about there. ETH is not recommended, it might stay up for now but from an objective standpoint it's basically trash.
Always keep majority in BTC. If you find that a couple of them are low afterwards, find out more about them.
