Yes the title did catch my attention! A marriage that started through Hive! I shouldn't have been surprised I guess - I think the interactions here can be a lot more genuine than many so called 'real-life' ones.
As to your question about what people are investing in. Other than growing my Hive account itself (target 10k HP by the end of the year) I've invested heavily into BRO in the last few months, and have a few other Hive Engine based holdings as well - mostly those that pay me liquid Hive in some way. Check out my most recent blog post if you'd like a bit more detail.
Anyway thanks for sharing and have a great day!
