In 5 years its a whole new area, and if you get in early its better than bitcoin.  

The fake ones are about making 10k on bit coin???

Does anyone have experience with crypto or bitcoin mortgages / lending?

There are those that discussed Gold and Bitcoin in the past.  

Last year my largest holding FDUS, paid 13.6% dividend and stock also went up 8-9 %, as long as 10 yr flat to rising they make money on their large net interest margin spreads.if you ok with moderate risk, pick good REITS, as a group VNQ they beat sp500 last 20 and 50 yrs by about 1.5-2.0%, and they beat private real estate investors by 2-4% in academic studies as well, that's an average, that doesn't mean REITS outperform the excellent investors here at BP :)Or take out a margin loan and YOLO Bitcoin, no don't do that!

I don't see a reason to go borrow at 8% and miss out on all these cheap equities and Bitcoin.

And not just Bitcoin (which I own) but the “meme coins” too, it’s getting 2020/21 wild!

It's slowing down though, most of their money the last 30 days has gone to gold, silver, and bitcoin.

Bitcoin is a strong long play, ETH probably as well, I have a large position in both.  

I would short bitcoin.
