This is happening to me as we speak... i was trying really hard to persuade them to risk some pocket money to buy btc back in 2011-12. Got tired trying and just stopped talking about it. Now they tell me that i am lucky bustard.
Doh, it's hard to understand people : )
I really hate such 'friends', frankly I think it's assholish and I disconnect from them.
A friend should support you, help you, not work against you and then when you do succeed, dismiss it with 'lucky'. It angers me.
After many years of suffering I think I understand people finally, there are just a lot of assholes and bitches, especially among 'family', replace them with nice people and your life greatly improves!
