Well if we are talking about paytm its a well known app many people use it. But the only thing which I dont like in this app is that it take tax on every wallet to bank transfer. I have also used phonepe, payzapp but only paytm is taking tax I dont know why. They basically charge 3 rs on 100rs transfer. And if the amount is big the tax charged by them will also be big.
Paytm has also launched its paytm mall app this app os basically the mirror app of paytm the only difference is that you cannot transfer money from your wallet to anyone or to bank. Actually they are making fool by this app. You can add you wallet money from paytm wallet to paytm mall wallet but you cannot add or send money from paytm mall wallet to paytm wallet as it can only be used for purchasing or recharging your mobile
So this is bad about paytm
