Sometimes diversification of investment also increase your income.
But to achieve this, one has to be very carful of the platform to which he wants to pour out his investments.
Platform?
It's always recommended to send all coins to your own wallet, where you own your private keys.
Not your keys, not your coins.

Diversifying into different choice coins is a good idea, mostly when you know what you are doing.

Diversifying into different Altcoins has proven to be a bad idea. I've made a new round of comparing Altcoins and Bitcoin, this time the Top 10 coins on December 24, 2017 vs. today by investing 900$ in:
- 900$ in Bitcoin
- 900$ in 9 Altcoins (100$ each)

It's a very bad result for Altcoins once again:
