you should really consult a professional about this but so far i have not read anything reliable about bitcoin being banned in India and only random newbies on social medias spam about the ban with falsified information. what happened was that the Reserve Bank of India stopped letting people use their bank to buy bitcoin and people are misinterpreting that as a ban!
Is blockchain wallet safe? can we store our bitcoin in blockchain over a long period of time?
I use blockchain.com's wallet and I had no problems with that.
blockchain.com has had lots of issues even security issues in the past, the fact that you never faced any doesn't make it any safer.
It is just based on my experience and it's a web wallet which we can't trust with large sums of bitcoin if its good for storing for a very long time. I suggested him to still get into hardware wallets as its the best to use.
It's up to him if he will avail or not, I don't know if he has budget to purchase one but I think he's able to get one for himself. OP may I ask one more question, are you really from India? you should be aware of crypto happenings there.
