I am glad you bought your first payment and had some fun with it. Though there are some paramount things you should know.

Never ever think of gambling as a sound way to make money, always have predefined limits and strictly adhere to them. Don't let it interfere with your normal life. It should just be treated as entertainment, not doing so will engulf you into a delusional view of the world, which can lead to a lot of harm. Not following this advice consistently can insidiously lead you to addiction without you even knowing it.

My intention is not spoil your fun, but money can be tantalizing, if you feel the urge to make some more - gambling your winnings may be the thing that comes to your mind, given that's it so convenient, is the only way you are aware of and you may not have other skills that can be used online. And given that your first online payment is from gambling - it could create a bias for gambling in your mind, a method that really can't be consistently used to make money, let alone be extremely dangerous if one doesn't understand that. So don't fall into this line of thinking if it does appear in your mind and store your bitcoins for long term!

You have to be diligent to protect your bitcoin, which means never giving your seed phrase to anyone, not storing it by dubious means (a text file etc) and using trusted software. I also don't think you should disclose the amount of bitcoin you have on the internet. When you get to anything significant, disclosing the amount and details can focus you in the view of malicious parties.

Good luck!
