"Trump selling his own token, is it a joke?"
No, it's not a joke, and I never consider anything relates to money is a joke. Your money is real, and you can spend it to get more from profit, or spend it for bad investment and lose most or all of it.
If this attempt helps Trump to collect more money for his Presidential campaign, it's real success for him, not a joke. It's not joke at start and at the end too.
Many trust that if Trump wins, it could bring a positive effect to the Bitcoin space. What are your thoughts on this?
This thinking can be true or not true, but even Trump as a President can bring positive effects to Bitcoin market, it is only short term, only four years for him to do this. Bitcoin adoption is like a Snowball that can not be stopped because after 15 years since 2009, now it is strong enough for name calling it as a Snowball.
After a next Presidency with either Trump or Harris as a President, Bitcoin will continue its growth.
Bitcoin is not dead and will not die next four years.
Will Kamala Harris or Donald Trump succeed to kill Bitcoin market?
They won't.
