At first glance these seem like some generic advices for a company as most of them have nothing to do with crypto space. Lets unpack some of these:
1] Your skills are precious enough to be a monthly charge
I mean what does this even mean? In what scenario this applies to DeFi? Sounds like you want to work in the company that respects you for your skills and pays you monthly salary?
But if you made that company, aren't you responsible to cover that?
2] You don't need the clients, They need you more
This is just not true. Uniswap needs customers as much customers needs uniswap. Users fuel it, while uniswap provides the infrastructure for the actions users want to do.
3] charge highly, Deliver better
I have no idea what you would be delivering that would mean. If the tech is more expensive to use, then i get charging more,
but if you want to charge more just by your profit, i think you are in the wrong business.
4] Any skill can be monetized - so far it has generated profit for you.
I don't have a clue what this means in this context. If i am reading it correctly it's more like a statement of getting profit from a skill?
5) if you are looking for your first client, you already found one, me and you
What does this even mean?
6) Testimonials help you sell better and faster - get yourself result first
Every time i see testemonials in the web page from random people, i am thinking it's 100% scam
7) Don't ever sell your services -anybody can sell services, but not everybody can sell profits v
Sell profits? Are we lost in translation here? People sell their startups all the time. I mean would you fight against big players like google or get aquired by them and invest that to your next project?
Always share your Testimonials
You already mentioned testimonials,
9) Brag humbly - it brings more client and increases your authority in that niche
Doesn't really work on this space. Bold marketing, and down to earth meme-like marketing that doesn't take itself seriously works better then toning the attitude down imho.
10) Partner with other agencies to increase leverage
Why not partner only that serves an actual purpose? Not sure what you mean by leverage here.
