bitcoins , gold ,lands or real estates is a good investment actually almost all are good investments if you can only handle it well and you can manage the money you earn to out it up on other investments .
There would be no doubts, these are the good investments of present times. But the catch is we need to choose the right one based on how much returns we could get back with them and how quickly we could get.
For me the good investment of Bitcoin is through trading because you, yourself are the boss of your business
Yes, when we are into a business based on bitcoin, there will be lot of benefits like we are having bitcoin and then having a business based on bitcoin and moreover like you said we are the owner of the business and hence we will be getting more profits than working for someone else.
Without doubt, bitcoin must be the best investment and making those investment working for ourselves will make that best investment into greater.
