Hello, you make a good point. What I will chime in on is this. Everybody wants the best. Blockchain technology is currently the best. As long as blockchain tech is pretty much un-hackable and newly re-inveted for different purposes it is here to stay. In terms of adoption it will only go up from here. Currently nothing can beat it.

Some sites not all require your SSID and license etc. Others just require an email and some coins. Depends on how what tokens/coins you are trying to buy.
