The process of buying DGB (or really most any crypto) is entirely too convoluted and weird for mainstream use. In order to get BTC, I probably have to deposit money in someone else's bank account or send a wire transfer or something and why the heck would I do that if PayPal or my Mastercard works just as well? Not to mention that I now have to transfer BTC to an exchange, trade it for DGB and then get it back. That will take me hours if not the better part of a day.
I just finally managed to get my father-in-law to stop thinking that anything involving Bitcoin is slightly shady and therefore worthy of avoidance. It's helped of course that every day there are more and more positive stories in the news around it, rather than the latest arrest, scam, theft of or drug deal etc. So I was able to engage him in a conversation around Crypto's and the Blockchain technology in general. I had him to the point of actually wanting to buy the DGB.... and he asked me how he could do this. And there's where I lost him. It's exactly as Ryven pointed out above... for him to do it on his own (even with my help, and believe me I offered, but he's independent) involves too many steps at the moment. He's in Vancouver, and I did point out that if he didn't want to wire funds to an online exchange to buy BTC first, he could go to one of the 3 BTC ATM's in Vancouver... but even then, it's kind of more complicated as he then has to import that paper wallet onto an exchange and carry on from there. Of course, easy for us... but not so easy for many.
I told him he could actually skip all that if he just wanted to have a few DGB to feel involved, and to worry about the rest later. I told him to download the wallet, let it sync up and I'd send him a few thousand to start him off. I even told him I'd put a message out on this board and that I had no doubt the community might even throw a couple hundred his way to get him into the spirit of things. But, to date, he's just not bothered... but I'm seeing him in a few weeks so maybe I can walk him through it all in person and get him fired up again.
The point? If the above is a TLDR... then the point is this.
The easier it is the get them and spend them.... the more "normal" people will get involved. This is a good point, and one most if not all cryptos have, even bitcoin. Except for those with an Android phone its incredibly difficult to actually spec them on the go (i.e. away from a pc). This is also one reason why Bitcoin has done so well in online shops rather than regular brick & mortar (well, also the confirm time doesn't help).
Rather than make a play for every kind of commerce, perhaps it would be good to focus on one particular kind & then develop the tools to aid integration amongst "in-betweeners" - that is people who aren't necessarily tech-minded but who are interested in such things & keen to have a go (such as tdcooper's Dad).
..just an idea
(and yes I know Apple recently allowed cryptos back into iOS, but I would be worried about them pulling the plug & me loosing all my funds personally. Until they have my trust that it won't happen again at least)
