1 Chain Link - Oracles BEST OF THE BEST
2 QKC - In my opinion the most undervalued coin also the top team, top investors and a lot of partnerships
3 BTC - It is the father of all coins and the entry point and exit point for institutionalists
4 ETH - The only working smart-contract
I like your choice, two more or less stable coins which will give 100% of their profit, and one undervalued and very promising. I have a similar portfolio.
