I don't like the risk of getting scammed etc and I don't want to always be extra cautious online so signature campaigns are perfect.
There is also an easy and safe way to get bitcoin and that is with trading. So upon earning from your signature campaign. You may try to invest it to trading and for sure that is going to give you better profit. And that is the most trusted type of investments, because most of the investments you are saying to be scam are the hyip's and cloud mining.
I don't think trading is safe and easy way.Trading is safer than gambling and trading is the best way of investment But it's not so easy and safe enough. Because trading is also like gambling. You need a bit of luck to be succeeded and Also need skills, proper knowledge about trading. So, it's not easy and safe.Lastly, many trading sites also do scam beaware of them.
