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?
I like bitcoin, ethereum.
Ripple I don't like at all, controlled by few whales, pump and dump coin.
Cardano - I wonder how it got so much market cap. If you bought cheap you can hold.
lisk - They have some flaws in their code, might dump
Others are not worth commenting because you have very limited amount
