People talking about coinbase is scamming!! Is it true? I want to know about this topic why they are telling like this? If this type of wallet scam people then what happend!!
So far, I haven't heard anyone accusing coinbase for being a scam. I do use them (though I would never recommend anyone to use any kind of web wallets), and never faced any such problem. Though, their support is really bad, like really "bad bad". Had an issue once, where my card was charged. I contacted my bank, they said everything was okay on their side, the problem was with coinbase. Took me over an month to solve "this simple" issue I faced.
Another reason why people might call coinbase scam (and why you shouldn't be using it) is because you won't have access to the private keys of your own wallet (though coins actually aren't stored on your wallet).
