Need some guidance before I buy 10k worth of ETFs/stocks

Hi all!

Been steadily investing a bit of my money into the following:

- WTCH ~1k

- VWCE ~1k

- CSX5 ~ 1k

- SWRD ~ 1k

- SK Hynix stock ~1k

Before justifiably roasting me, I bought this when I knew less than today and I don't think I should sell any of them to buy other ETFs.

I decided that my savings are just sitting there so I want to invest 10k. What should I do?

1. Buy VWCE and chill? In one go or over several months?

2. Buy another ETF and if so which one?

3. Split 80/20 between VWCE and more stock to have a giggle?

Thanks in advance!
