Actually a lot of other things would be cool too . Exchanges are plenty , and for within India only 2-3 will do . I am also interested in starting up or working in a start up specially bitcoin related in the future. I really think something along the lines of startups in Philipines would probably get a lot of interest here in India.
Anything to do with money transfer, you have to be very careful. Too many regulations for NBFCs.
Yes, but probably even in those countries these regulations exist and the companies were able to follow each regulation and launch their company successfuly. It probably has a bigger scope in India than in some of those countries.
