If something is hard to obtain and is not going to change your life for the better, you are not going to give a fuck about it. This reflects on the price. If you keep shrinking ways to obtain BTC besides risking your FIAT, Bitcoin will just be an asset where wealthy people store their FIAT in hopes it doesnt crash, just like Gold. It will never be an actual currency.
Completely agree.
The other perspective is that you have to ask yourself who is clicking signature links?
I used to have a CEX signature link and it amazed me how many times people clicked it. Did those clicks convert into sales and commission for me? - not often.
There's many motivations for getting involved with this bitcoin forum and signatures are just one way of getting eyeballs on whatever the member appends as their sig. It used to annoy me seeing all that gambling drivel in people's signatures, but if it earns them a few coins, good luck to them. I very rarely click a signature link but the ones I do click from time to time include new product launches and some bitcoin services.
It seems too draconian just to ban all signatures but would I care? - no.
