Bitcoin as with dollars or other currencies is not "scam proof" . The biggest scam that i know with regards to the development of bitcoins was about the "Silk Road" , but i think the silk road is not a scam but it was a store that are selling illegal items like cocaine and guns. The other big scam was the site in Japan "Mt Gox" that put up a bitcoin exchange which handles the bitcoin and not the bitcoin software that is why the :loophole became the source of robbing the members of their bitcoins.
I was aware of this big problem with some sites using the "bitcoin technology" to make themselves millionaires in a short of time. I had not been a part of these , i only knew these with the news that it happened.
What i want to share was that about my own experienced with these "scamming system or program" utilizing the bitcoin ( mind you its not the bitcoin technology is not the problem) , it is the people who are looking at the 'LOOPHOLES IN THE BITCOIN SYSTEM" and utilizing these loopholes for their selfist ends.
" I experienced to send 0.01 bitcoin to a site http://x100.virb.com ( these site is no longer online about these week) . These site promised to pay you 100 percent of what you send them not exceeding 5 bitcoin. So i was attracted to this because this is different as to other sites that only offers a few percentage but this is 100 percent. I check their transaction online on blockchain.com and its there , so i decide to join in. Now the problem its about a week now , where they promised to pay in 24 hours only. in a few days i can still see their site but about this week its no longer online. Its a clear SCAM. now the LOOPHOLE, the bitcoin wallet address is not a guarantee that you can communicate with them , there was also no Email address to contact them, its a question of TRUST that they see as the LOOP HOLE.
The transaction is on the "blockchain" the wallet address on the left is mine and on the center the wallet address above was from the "SCAMMER" , and the site is no longer online which was supposed to be http://x100.vrib.com
It is a clear "SCAM" the site is no longer online, it is easy to change bitcoin address and also easy to change sites .. I believe i had surf this x100 Grow Your Bitcoin in other IP address , so watch out for this program. Go to genuine programs on EASY WAY TO EARN BITCOINS , just click on the bitcoin surely they will pay you.
