I ran a finance forum with over 3,000 folks in it, at work, before I retired. Young folks would often ask me "what do you think about [financial matter/investment]". This came up about crypto. Essentially I said that I have no interest in:

- a currency (for want of a better word) subject to wild swings based on the tweets of a mercurial, possibly drug using billionaire,
- a currency that takes 20-40 minutes to complete a transaction,
- a currency that seems to be eagerly accepted for drugs and dodgy porn on black markets on the internet, and
- a currency unusable for any real transaction...as in the last couple years (knowing the reaction would be of the "are you insane" type) I asked a car dealer, a real estate broker, and a general contractor if they dealt in crypto.

For the last one, as they say in a Christmas Story, they looked at me like I had lobsters crawling out of my ears.

Of course, these young people are gonna FOMO/HODL, regardless of what I said, so I told them that as I knew they were going to do this anyway, keep it to 5% of their investable assets.
