Skrill is better than PayPal but still users can chargeback if the funds are uploaded via CCs or stolen cards. Also, they can hack Skrill accounts and send you funds. You need to trade only with a trusted user when using Skrill as a payment method.


P.S: Would like to mention about Indian wallets like Paytm, Mobikwik, Citrus and so on. These wallets too are unsafe and users can send fraudulent funds via them and I've lost my 0.15 BTC due to this. It's similar to sending money via hacked bank accounts. So again there are barely any payment processors here that are non-reversible and safe to use.
