Holy smokes. This is getting interesting and inviting. I really want to invest but why am I so afraid. One question. If I do it am I too late to invest?
Not to late, just start small and get to know the sites you invest in.
I saw one thread and op was investing 1 btc each on these top betting casinos betking, safedice, crypto-games, satoshi dice and another popular site I forgot the name. He was posting updates weekly and currently it's on week 7. Safedice, Crypto-Games and Betking are currently at least 15% gains while the other 2 are less or some losses. So maybe you can start with those 3 top investing casino sites.
I think they can disapear easily with your money and you have a very low profit. High risky!
At the moment i find bitcointalk a good source to find good bitcoin related investment projects. Be it ICO's or regular altcoins, there is enough to choose between.
So much I have to buy new bitcoins every month to keep up with these projects.
Investing in ICO's are going to be a good way to invest your bitcoins and not just with those ICO's because if you think and researched that the developers of that alt coin for sure you are going to invest more on that project if you think that the coin is going to pump in the future or else you are going to stick with trading.
ICO's are the best option to invest, however we can se a lot of scams over there... Have to search and study a lot before put some money.
