Just to make it clear - all progressive systems are pure evil. They might be very fun, as you can succeed many times to achieve your initial goal. But remember - one bad run can bust your whole bankroll.
The worst thing that can happen when you find a good bet is to wait while your bank approves your deposit… Using e-wallets for your transactions from account to account is instant and transfers to almost all bookmakers are instant, too.
Before you create your new Skrill or Neteller account, check and think twice which currency you use the most in sports betting? Which currency do you use in your country? In a perfect world it should be the same everywhere.
For money transactions try to use only your own phone and computer. If you must use public computers think twice... is it in a safe area at least? And always use incognito browsing to not leave history after browsing.
