Would Go, PHP, Javascript, HTML5 Do The Trick?

HTML and Javascript, I have to brush up, Go and PHP I have to do from scratch.

Idea:

create a forum/blog-like website
allow for moderation in stead of downvoting
you can like, dislike, and maybe something else (rate stars, emoji, ...)
you can earn and pay tribute to authors and commentors through a Bitcoin-tethered T-TOKEN
before you can earn or pay, you have to create a BTC-T-Token Wallet and deposit a minimum amount of Bitcoin
once the tokens are in the wallet, only the owner of the wallet can access them
the blog/forum website takes 1-5% fee on every token transaction to make things going
at least once a day, a user can exchange his tokens for BTC and withdraw his/her/its (LOL) bitcoins/satoshis to an external BTC address

is this a good business model?
would PHP, Go, Javascript + HTML5 be enough to build such a site?
Or would I have to learn/hire database languages/specialists?

(will be updated as brainstorming progresses)

There would be no Intial Coin or Token Offering, since the Token would not be listed on any exchange but on the exchange of the blog/forum-linked exchange platform
No speculation with the Token, as it is meaningless because it is tethered to BTC
There could be 2 kind of blog posts:
a. NON-blockchain posts that are free (if you have a T-Token account)
these NON-blockchain posts are NOT incorporated in any kind of blockchain and can be completely deleted, erased, edited by the poster and moderator-team
a1. the possibility of an expiry-timer could be implemented to make a post or thread disappear after a certain period or on reaching a certain time or date.
b. BLOCKCHAIN posts that have to be payed for, because they will be reviewed before being published
b1. Blockchain posts remain in the blockchain but can be made invisible on the User Platform by the author or the moderator-team
Weaknesses?
Threats?
