I had used the unocoin app for trading bitcoins before 2-3 months ago.first of all, we will know that, what the purpose of unocoin, unocoin is used for buy and sell bitcoins at any cost.you can buy and sell bitcoin after verification of your profile.there is very poor service for vrrification.verification done in 14-15 days.this is very long time.there is very bad service of customer care no.it provide coupan code and refferal code for earn 210rs.it can use after verification.200rs for coupan code and 10 rs refferal code.you got 10 rs in paytm after 20-30 days.and coupan code can’t easily find, so, conclusion is that you shouldn’t use the unocoin app, thank you
