What is there to invest Bitcoins in without having to cash out to fiat first?
I was looking for ways to buy physical gold (held in bank), stocks/shares, stuff like that, but options seem very limited.
Any ideas?
Just get a super mining rig. Watch the money flow in. However if you do decide to mine, you should mine altcoins. Bitcoin mining has been taken over by the rich.
You can also trade in alcoins.
