How do I securely store different CryptoCurrencies?
Short answer: Yes, it is possible. But depends on every coin. The majority of the top coins has his own wallet where your funds can't be stolen.

First of all, taking into account that cryptocurrencies are a developing technology I wouldn't use the word "securely". But if you want to minimize the risk, I recommend you to diversify your portfolio, for example:


50% BTC
20% ETH
10% LTC
10% XMR
5% IOTA
5% MAID


That would be pretty much my choice, you can make your own.

In any case, for a long-term investment I recommend you to research the core technology of each coin. And of course guard the funds on your own wallet.

If you want to invest on really new cryptocurrencies that doesn't have a wallet yet, you'll have to let the money on the exchange until a wallet is launched. There's no other way.
