A couple of years ago I and my friend had a project. I had some experience with bitcoin cryptocurrency and I invested in a project with bitcoins and lost a lot of money because of hackers who stole all my data. Well, since then I found a way to protect my personal information. And now I use the bitcoin mixer service that hides all my transactions and makes them untraceable. I keep my anonymity and privacy and stay absolutely safe. This service clears all your data after making the transition. It's https://mycryptomixer.com/ very easy and safe to use.
