Which websites are best to invest money in Bitocoin ?

Just invest into crypto's through the place you buy them such as exchanges, normally websites offering 1% per day on the money you put in are ponzi schemes and in fact are illegal as offering unrealistic returns on your money.

Or give me 50,000 and Ill be more than happy to give you 1% back per day. Get someone you know to give me another 50,000 and ill give them the same deal but I'll give you 10% for bringing them to me. It's the same principal.

Most are scams so be aware.
