Business ventures are always a good idea if you have the right people. I have been trying to get one of my new businesses of the ground and originally 4 people is now 3 and now realising the other 2 are not great as you have to keep on pushing them. If you have a business venture that needs another investor just shout as those projects are really good fun.
Crypto will become mainstream like shares in the future and having both is always a good idea for safety covering all bases.
