What are you talking about ? What investment websites ? There's no such thing as btc investment websites.
You totally have the wrong approach towards crypto currencies and don't actually know what its all about.

When we say "invest" in crypto, we mean you buy a certain coin that has potential to grow in the future and waiting till it becomes selling more than the price you bought it for and then selling them. Anything else than that has nothing to do with investments.

I guess you've seen a few times here and there websites and people promising to give you back crazy profits back for your "investments" on their shady websites and you probably believed them as you thought that's the "crypto" thing that everyone is talking about. NO you're totally wrong. These sites are scam and these people are thieves who are trying so hard to get their hands on your money.

Never trust any of these. Read more and more about how to buy crypto and how to sell it for a profit rather than looking for an "easy" way to earn as you won't get anything out of it except losing your capital. Right now you're basically a very easy target for the scammers.
