Do many people around you claim that bitcoin is bad? yes this happened around my place.
I don't care what they say, even though I haven't been here long, but I'm sure bitcoin isn't as bad as they think, this is a future technology where when the future comes, we are ahead and they are still behind

. I am sure of that!
Why would you care, they can say what they want to say and do and you can still make a profit from Bitcoin, it's their loss, not you, think of it as a blessing that you know something that you can make a profit and they failed to do what you are doing, they will eventually ask you in the future, when they notice you are financially free.
