I sold most of my Crypto holdings so that I could pay for a brand new house for my young family.

If you own a house, it's more valuable than a number on a screen. Don't feel sick, I think HIVE is going to ride this wave up and who knows... maybe it'll be the opportunity to buy another house. :-)

I don’t like to live with regrets but I also feel like I am not going to get past this one.

Don't live with regrets, make the best of the investments you currently have and pay no attention to what's going on with what you don't have, even if you once did.
