A testimonial that makes me feel the hard work is worth it

It's been 2 months since we launched TinySnap, and today I got a testimonial as in the image, I am so excited about it.

He says: Thanks for creating TinySnap for free. As, a student, it is impossible for me to pay right now but after I get a job, I will donate heftily to you via crypto. I will pray to God for you until then.

Do you get any uplifting testimonials in the journey of indie hacking?
