Recently I have entered in cryptocurrency earning so I thought which is the best wallet for buying and selling Bitcoin so my friend ref Unocoin which provide buying, selling, transfer , deposit, withdrawal and also recharge mobile and DTH. so I had sign up with my friend referral code and also entered coupon code which was working on the time of sign up I saw that this referral code gave me Bitcoin of 200 rupees worth after mob and email verification. which was very high giving by Unocoin compared to other wallet. After that I verified all the personal information without any problem and inconvenience. If you want to enter in Bitcoin so you need to install Unocoin
