Your friend was a bitcoin hater, but now, having seen the living embodiment of the opportunities you realized, in the form of a house, motorcycles and a stable financial state, he changed his vision. There is nothing surprising in this, because all doubts are dispelled when we see the results of successful investments from our friends and relatives. This is what opens your eyes and comes the realization that btc is really a unique thing that allows you to change your life. This is what works to convince the people around you, and not when the poor man screams that he will make you rich, but at the same time, he himself has nothing and can't show. In terms of material wealth. Words are not convincing, but facts and visual demonstration are a powerful tool to change views about bitcoin.
and also the way I can prove it for real with what he saw with his own eyes and that's proof that doesn't need to say much, and I'm also the type of person who doesn't want to say much because real evidence can amaze people and I just want to prove to him, that bitcoin is not what he said it was then.
