1. Yes, there's no restriction on where you live. Bitcoin transactions are covered worldwide regardless of the state's policy, you can always receive bitcoin from anyone as long as they send it directly to your wallet address.
2.Yes, you just need to send it to the zebpay bitcoin address of your account, not others account but yours.
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. But if you are looking for the highest quality of wallets, buy a hardware wallet. My personal choice is to get your very own ledger nano s.
PS: Would you clarify if India do really ban bitcoin transactions? AFAIK with the news online, they only give caution to the public.
