Can someone help me with my portfolio?

EDIT: I am looking for a long term investment (6-10 years)

Hey guys, im new to crypto space. I have my investments in stocks and last week started my research on crypto and I got convinced to start investing. Then sold some of my stocks and here we are! I started with 15k and here is my crypto account portfolio so far based on percentage.

Biggest three makes up for 84% of my portfolio

BTC - 61% SOL - 15% LINK - 8%

Others - 16%

RNDR NEAR HBAR GRT DOT DOGE SHIB

I did extensive research on BTC, SOL & LINK. I will be keeping those 3 and add money to them every week. As for the others, which should I get rid of and keep? I feel its too spread out. Thanks for your time in advance!
