Well first off compared to US, the regulations have become very strict in india which combined with the bear market scared away most miners and secondly its not easy to trust someone who says he will deploy miners in a country thousands of miles away. It smells of a scam and even putting that aside most people who did this model have given up due to how unprofitable the market became.
You are right that the regulations are confusing and the general idea is that Bitcoin is seen as shady by the establishments as compared to US. Whether this "scared" the Indian miners away or not is a question i wish we could have answered from someone actually involved in this. I recall seeing youtube video of this guy running bitmain miners in Gujarat and other places. The videos are from 2016 or so.
Wonder what happened to those guys and how exactly they are sourcing the miners lately.
This paying for deployment thing is possible if you are in the same jurisdiction. Of course it is little other than a cloud-mining thing if it is overseas. Though i am sure if done on the forum through an established account, this could take some shape. If you are interested in seeing how the overall mining buying and deploying works for individuals then
this is a great board.
