If you already have an eCommerce business set up, you can instantly begin accepting Bitcoin by connecting your store with a BTC payment processor. Most eCommerce businesses already have existing integrations with payment gateways, which makes setting up Bitcoin payments considerably less demanding.
Once you've settled on a Bitcoin payment gateway and have set up your system, you'll need to guarantee that all exchanges on your site — and additionally your funds — are secure.
1. Stay up-to-date - Try not to disregard your software updates. Make sure that you're continually using the most recent rendition of the Bitcoin wallets, applications, or solutions you have so you can remain up-to-date regarding security and stability fixes.
2. Strong passwords & multi-factor authentication - Ensure your wallet’s safety by using a solid, difficult to-figure secret password (or even better, a passphrase) that contains a blend of upper and lowercase letters, numbers, and special characters. In case the bitcoin payment processor that you're using offers multi-factor authentication (e.g. expecting you to enter a code sent by means of SMS or email), you should take advantage of it.
3. Backups - Backups can help defend your funds in the event of a security break (e.g. in the event that somebody hacks into your system or if your device gets stolen or broken into).
4. Not keeping huge amount of funds in your wallet - Keep in mind, hackers and thieves can't take something that isn't there. Make it a point to every now and then transfer your funds offline or convert them to your local currency so you can have them in your (protected) bank account.
