So in case, you don't know how blockchain can save you a lot of money when you make a form for social network or service that takes you to host a lot of files that also is being uploaded by its userbase for eg. DTube that make use of the steem blockchain to host all the files that are uploaded to the website, but instead of being hosted on the main server all files are hosted on the blockchain and called back when someone is watching that specific video that they click on.

This way can save you on SSD Space, Ram mem and CPU cost on the main server that host the PHP files of the website since it won't have to deal with 1GB+ full HD files laying on the server.

Blockchain can also give bigger security for user information like images, KYC stuff and so on and keep it from idiots that just want to steal it for their own profit...

So this will not only make it cheaper to start a company but also making it possible for almost everyone to start one since you can kinda find any information to install things online no matter if its blockchain or coding a full out website that will be using the blockchain.
