r1s2g3: I'm not demotivated by criticism. Constructive one is perfectly okay with me. It's where expectations meet reality. For example, I didn't expect so many people to take the app that seriously. Anyway, I made a few updates reflecting the things mentioned here.
Funny thing is, I am aware of Do I Own a Shitcoin. I had that little idea of mine even before that web materialized, but I got round to deploying it only recently. Even though the concept looks similar, I think it's rather different from what I gather (if I remember correctly, Do I Own a Shitcoin is based on human analysis).
Besides, my objective with Hodl or Not isn't to provide an app that would aspire to become the touchstone of cryptocurrency trader's toolset. I wanted a very simple yet relatively relevant app to test out a few things regarding bandwidth, traffic and similar stuff.
