To start earning and using bitcoin now is that there is no chargeback in bitcoin. Once you trade bitcoin or transfer the currency, it is gone. No way to reclaim the money without the recipient's permission. Thus, it discourages chargeback fraud that is common with credit cards usage. For instance, when someone buys goods and he discovered that it is defective, he may contact credit cards agency to make a chargeback, effectively reversing the transaction and resulting into loss for you. The credit card companies do something like this often. But, with crypto- currency, it is completely safe.
