Where to invest bitcoin?

Bitcoin can be invested in stocks, and other forms of business. It can also be exchanged in many forms of altcoins so that if a certain price of an altcoin increases, you will make profit.

You will not gamble at a gambling website but they offer a good amount of return when you invest with them.
Try the gambling section but do not go to the games just the investment.
I find it better than choosing a cloud mining which is just always a scam.
Or you could also try to be part of an ICO, just a little risky. With a good knowledge you will be getting double or triple the money.
Look at projects where they have already started the service. Just an ICO for upgrades.

You can choose a lot of it here in forum but if you are getting an eye to those "double your bitcoins" they are truly scam so forget about them. You can find trustful exchanges and trading platform, why not start trading with alt coins? But paying a farm game? That's quite new to me I don't know that there's a game like that. There's no other place where you can get good return unless you'll getting yourself ready by trading with alt coins.
And since you don't want to gamble you can try to invest with some casino's bankroll investments, it's also a good place to invest your bitcoins.

Of course. I am investing my bitcoins in Forex brokers, but I can afford this because I know the business and have extensive experience in it. I would not recommend it to anyone because it can involve great risks that not everyone is willing to take.

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.
