If you want to stick to credit/debit cards, the best alternative to Visa is MasterCard. These options are very similar, both globally accepted with perfect security and offering generous rewards schemes. This is because they are the main competitors to each other, so when one offers a benefit, the other quickly matches it. However, the details do vary between companies, for example, credit limits may vary. Among other safe and convenient deposit and withdrawal options are bank transfers, Skrill, and cryptocurrencies.
