I was literally struggling when blockchain or rather btc was dropped as a surprise to techies around the world.
It was suspected to be a scam by most of the people on the other hand some of them tried execution, mining hell lot of stuff with it and they are sitting on the top.
So the lesion from the story is not to call every coin a scam and believe your instincts rather blindly following social media views
Whosoever bought the coins so far must have observed the transaction speed and reliability using their platforms.
