The worst investment venture is gambling unless you own the gambling site then it could be profitable but as an end user gambler your doomed to fail.
The best is keeping your bit coin or investing your coins by starting a service with which you will yield.
that way of thinking is what leads to lots of losses because people think they can make money if they start a new business like a gambling site and as we can see there are lots of gambling sites specially dice sites that keep failing because their owner is not experienced enough and they end up scamming just to make ends meat.
that is why it is wiser if you start small, gather a group of people for brainstorming and as partners and then start small and build the business over time as you gain experience.
i think the idea is good, it needs courage to start one and will give you the best yield, aside from that you have control over the path of your business, decisions is all yours to make. and besides, you also don't know if the investment you made to other company will succeed or not.
Here is a better approach in my opinion, if you are good in one service and knows everything about the ins and outs of that service, it is wise to put it alone if you have capital to do so. You do not need an extra head if you actually knows everything about it. You can hire people that is good in that field and can get their idea about every situation. Partners sounds good but lots of partnership gone broken because of the misunderstanding between the co-owner.
