Why would "Grandma" want to exchange fiat for blackcoin to buy things she could buy with fiat in the first place ?
Let's not kid ourselves here, if you're trying to target Grandma or even average Joe then you're targeting the wrong demographic because using anything but fiat would be an inconvenience to them and they will not appreciate the value of crypto currency over the current shackles of fiat.
To make crypto's successful we need to bring in more people from the tech world first to pioneer these currencies before we get the general populace on board, if we had it so kids badgering their parents couldn't buy the latest games or technology without having crypto's to buy them with then it would essentially go a hell of a long way to breaking free from fiat which is the core ethos of crypto's.
Target indie developers, bring those people on board because they are the future for the ever expanding tech world and technology is the future
Did you read what I wrote? There are two uses for crypto-currencies.
1.) People use them to invest.
2.) People use them to buy things.
I am an investor but I also happen to be a techie. I have many Wall Street friends who would be thrilled with a 1000%+ ROI in less than seven weeks. However, trying to explain how to buy BlackCoin is a task. Yes it would be great to be able to buy real things with BlackCoin, but we cannot forget that what also keeps any currency relevant are the investors. That is also true for Fiat currencies (Forex)
So essentially you're doing all this so you can get people to pump the price then dump for 1000% ROI
What keeps any currency relevant is daily trading at a stable level, it's why fiat is so successful and so hard to break away from because I know that I can buy a Mars bar for 40p and will likely be able to buy another in 6 months time for 40p. The same cannot be said for crypto's just in a month BC has gone from 2k to 500 to 4k to 8k to 4k to 5k to 6k. For any of these coins to be taken seriously we need long term stability and people coming in for 1000% ROI are not the people we want to make these coins successful because they're just going to create even greater instability with their initial pump and eventual dump.
When we can back our crypto's against real world items be it niche gadgets or indie games or something completely out of the box in order to have stability then we can start attracting the general populace because as long as our crypto's are backed against fiat they're never going to stable or taken seriously
