I think Bitcoin will be more valuable in the next few years and maybe it will reverse but I have confidence I hold it.
Of course bitcoin will become something valuable in the next few years. Your choice to invest in bitcoin is correct and you are lucky to have a friend like him who wants to teach you and advise you to invest in bitcoin. There must be confidence in bitcoin, because without confidence you will be afraid to invest because you are hesitant about investing in bitcoin. Maintaining bitcoin is a wise choice.
When investing in something there is always risk involved. I think risk is the possibility of gaining or losing something valuable.
All investments have risks. In my opinion, the risk of bitcoin investment is not loss of value, because if you still hold it you haven't lost. The most feared risk is that you lose the prase seed , so here you have to be really careful when storing bitcoins.
