Serious Got 50 Visa Card free, how do I "Invest" it?

As title sugest. I got a 50 visa card for free, and instead of idiotically wasting it, I was wondering if there's anything I can do to actually invest it in something.

Turn it to BTC? You'll probably only get like 40-45, but if you wait till it's low then you could end up with over 60. I don't think you can do much with it other than spend it.

As silence said, turn it to BTC and you can start buying and reselling things or something like that!

I don't think that you should invest in BTC. Putting 50 dollars into a BTC account won't even do much until its been a few months, and by the end of that few months the value will either go up like 10 bucks or decrease 10 bucks. I would just spend it. You have 50 dollars, do something useful with it for the time being. If you really want to sit around for a while just for 50 dollars to go up to 60, which isn't even guaranteed, be my guest.

Well, what are you interested in?
Invest it into something that'll be helpful in the future, that's all.

it's 50 dollars, you will barely get any money to be honest.

If it's legit buy something, you won't have something really profitable from a 50 investment.
If you got it illegally don't fuck up with carding, just saying.

A good way would be to look into matched betting. Theres loads of help online. It's a great way to get guaranteed return from betting.. (If one bet loses the other bet wins)
