From my experience, all the double your BTC websites are scams.

Think about it.. How are they getting the money needed to provide you the extra BTC?

If it's not a scam, it's possible it's a pyramid referral scheme. (which sometimes pays out)
But then you gotta work hard advertising for the company to get your money back...

Proceed with caution if you want to test some of these out.

I agree and you should think just like them. If they think that they can fool you then you should also think how you can take advantage.
Just think ahead of them and don't believe their shitty promises. Just invest in trading, there are a lot of good coins now and this is the good buying point while the alts are still crawling.
However, in trading, when things turned out unexpectedly, there's no people who you gonna blame for your loss, is it all by you.
