I regret that I use the bitcoin that I bought to invest on a scam site. But I still think it is good if you will use it both as currency and investment.
Don't worry dude cause you are not alone, when I was new in this world I was also a victim of scam sites but I have move one and learn from my mistakes in the past, and now I am already happy with the my standing as I can invest already in legitimate business online.
These are all happens regardless of how you are using bitcoins. Investing into a legitimate business, will not assure you will not get scammed in future because a business may turn at any time.
But saving bitcoin as an investment must be more secure from my experience as no one will able to scam me if I have my bitcoins more protected and also in cold storage.
this is what make an ordinary people yelling bitcoin as a scam thing ,
a lot of people believe that bitcoin investment just s biggest online scam ,
too much scam attempt in bitcoin business world ,
hard to prevent this , so just becareful choosing an investment place.
