First dont look at adverts. That is not a good source of information because it wants to sell you something.
If you heare about something, make your own research and also search for the bad sides. Than decide rational what side is more trustful.
For example if you google "bitconnect," you will find a lot of positive because people are promoting it to get referral rewards. Google also "bitconnect scam" and you will find a lot of negative arguments. Then decide who you want to trust.
