Haven't nurturing this idea of trading a Bitcoin in the near future,but one question that's always come as a concern to me is. Is proper for me to trust a friend of that high magnitude ?
How about learning from them since they are into Bitcoin before you?
Mind you, start doing your own research too, and when it comes yo money do not trust them too much, friends are always trusted until proven otherwise, instead of getting your heart broken its better to learn yourself
This days too many friends end up becoming betrayers, learn to do your thing with your money alone.
