Within the period of time until 2030 bitcoin is more likely to become an asset and there will be another coin which is better as a means of payment. By that time, IMO, just like now bitcoin is being treated like gold.
And for STOs, are there projects that became successful launching? haven't heard any of it if there's any.
As far as I’ve seen, Initiative Q seems to be the only security that successfully launched well. As it started two years ago. As far as any other securities I have not heard any others myself. So, if no one can name a single one Q might be the only successful launch with a mere 2-5 mil user base currently. Could be more than that. It seems their goal is 10 mil user base but I am not certain of that.
