In general, I believe that you don't need to convince anyone that you are right. However, you have the right to your own opinion and are free to express it, regardless of whether it coincides with your opponent's. You can simply explain something, tell about your own experience.

Especially when it comes to cryptocurrencies. Everyone has had or has their own experience in this area. Some people have good experiences, some have bad ones. No one will ever be able to come to a single point of contact. Because even if you read the media, you can find different information on different websites, and everyone will think that the truth is on their side.

Therefore, I think it is better to express your opinion, but not to prove it to anyone or convince your opponent.

Good luck!))
