Hey guys! I am relatively new to crypto and I woud like to have some feedback on my Portfolio 
40% Ripple
25% BTC
15% Cardano
8% Lisk
5% Ethereum
4% Iota
1% Litecoin
1% Siacoin
1% Stellar Lumen
I have doubled my money with this Portfolio. I am looking to invest 50% of my initial investements in other Altcoins, any suggestions?
Get out of Ripple, they already messed up when it was tested by a japanese company. Additionally, Stellar seems to have the better codebase, so maybe just switch to it.40% Ripple

Cardano is way overhyped, lower this amount to 5%. I really like your other coins (though i would lower the amount of BTC since i believe it will crash by the the end of 2018).
You may consider investing some money into coins with lower market cap. For 2018, especially coins focused on development will be bullish (like ETH, NEO & QTUM), as well as coins attached to exchanges / DEX's (like BNB, Kucoin, Bitshares & Komodo).
